If every person on our blue Earth watched this video, the world would be a much better place. At least for a few minutes. Listen closely to Carl Sagan’s words till the end. It won’t fail to get you teary.-JD More »

  

CSS’ barrier to entry is extremely low, mainly due to the nature of its syntax. Being clear and easy to understand, the syntax makes sense even to the inexperienced Web designer. It’s so simple, in fact, that you could style a simple CSS-based website within a few hours of learning it.

But this apparent simplicity is deceitful. If after a few hours of work, your perfectly crafted website looks great in Safari, all hell might break loose if you haven’t taken the necessary measures to make it work in Internet Explorer. In a panic, you add hacks and filters where only a few tweaks or a different approach might do. Knowing how to deal with these issues comes with experience, with trial and error and with failing massively and then learning the correct way.

Understanding a few often overlooked concepts is also important. The concepts may be hard to grasp and look boring at first, but understanding them and knowing how to take advantage of them is important.

Two of these concepts are specificity and inheritance. Not very common words among Web designers, are they? Talking about border-radius and text-shadow is a lot more fun; but specificity and inheritance are fundamental concepts that any person who wants to be good at CSS should understand. They will help you create clean, maintainable and flexible style sheets. Let’s look at what they mean and how they work.

The notion of a “cascade” is at the heart of CSS (just look at its name). It ultimately determines which properties will modify a given element. The cascade is tied to three main concepts: importance, specificity and source order. The cascade follows these three steps to determine which properties to assign to an element. By the end of this process, the cascade has assigned a weight to each rule, and this weight determines which rule takes precedence, when more than one applies.

Please consider reading our previous related article:

• CSS Specificity: Things You Should Know

[Offtopic: by the way, did you know that there is a Smashing eBook Series? Book #1 is Professional Web Design, 242 pages for just $9,90.]

1. Importance

Style sheets can have a few different sources:

1. User agent
   For example, the browser’s default style sheet.
2. User
   Such as the user’s browser options.
3. Author
   This is the CSS provided by the page (whether inline, embedded or external)

By default, this is the order in which the different sources are processed, so the author’s rules will override those of the user and user agent, and so on.

There is also the !important declaration to consider in the cascade. This declaration is used to balance the relative priority of user and author style sheets. While author style sheets take precedence over user ones, if a user rule has !important applied to it, it will override even an author rule that also has !important applied to it.

Knowing this, let’s look at the final order, in ascending order of importance:

1. User agent declarations,
2. User declarations,
3. Author declarations,
4. Author !important declarations,
5. User !important declarations.

This flexibility in priority is key because it allows users to override styles that could hamper the accessibility of a website. (A user might want a larger font or a different color, for example.)

2. Specificity

Every CSS rule has a particular weight (as mentioned in the introduction), meaning it could be more or less important than the others or equally important. This weight defines which properties will be applied to an element when there are conflicting rules.

Upon assessing a rule’s importance, the cascade attributes a specificity to it; if one rule is more specific than another, it overrides it.

If two rules share the same weight, source and specificity, the later one is applied.

2.1 How to Calculate Specificity?

There are several ways to calculate a selector’s specificity.

The quickest way is to do the following. Add 1 for each element and pseudo-element (for example, :before and :after); add 10 for each attribute (for example, [type=”text”]), class and pseudo-class (for example, :link or :hover); add 100 for each ID; and add 1000 for an inline style.

Let’s calculate the specificity of the following selectors using this method:

• p.note
  1 class + 1 element = 11
• #sidebar p[lang="en"]
  1 ID + 1 attribute + 1 element = 111
• body #main .post ul li:last-child
  1 ID + 1 class + 1 pseudo-class + 3 elements = 123

A similar method, described in the W3C’s specifications, is to start with a=0, b=0, c=0 and d=0 and replace the numbers accordingly:

• a = 1 if the style is inline,
• b = the number of IDs,
• c = the number of attribute selectors, classes and pseudo-classes,
• d = the number of element names and pseudo-elements.

Let’s calculate the specificity of another set of selectors:

• <p style="color:#000000;">
  a=1, b=0, c=0, d=0 → 1000
• footer nav li:last-child
  a=0, b=0, c=1, d=3 → 0013
• #sidebar input:not([type="submit"])
  a=0, b=1, c=1, d=1 → 0111
  (Note that the negation pseudo-class doesn’t count, but the selector inside it does.)

If you’d rather learn this in a more fun way, Andy Clarke drew a clever analogy between specificity and Star Wars back in 2005, which certainly made it easier for Star Wars fans to understand specificity. Another good explanation is “CSS Specificity for Poker Players,” though slightly more complicated.

Andy Clarke’s CSS Specificity Wars chart.

Remember that non-CSS presentational markup is attributed with a specificity of 0, which would apply, for example, to the font tag.

Getting back to the !important declaration, keep in mind that using it on a shorthand property is the same as declaring all of its sub-properties as !important (even if that would revert them to the default values).

If you are using imported style sheets (@import) in your CSS, you have to declare them before all other rules. Thus, they would be considered as coming before all the other rules in the CSS file.

Finally, if two selectors turn out to have the same specificity, the last one will override the previous one(s).

2.2 Making Specificity Work For You

If not carefully considered, specificity can come back to haunt you and lead you to unwittingly transform your style sheets into a complex hierarchy of unnecessarily complicated rules.

You can follow a few guidelines to avoid major issues:

• When starting work on the CSS, use generic selectors, and add specificity as you go along;
• Using advanced selectors doesn’t mean using unnecessarily complicated ones;
• Rely more on specificity than on the order of selectors, so that your style sheets are easier to edit and maintain (especially by others).

A good rule of thumb can be found in Jim Jeffers’ article, “The Art and Zen of Writing CSS”:

Refactoring CSS selectors to be less specific is exponentially more difficult than simply adding specific rules as situations arise.

3. Inheritance

A succinct and clear explanation of inheritance is in the CSS3 Cascading and Inheritance module specifications (still in “Working draft” mode):

Inheritance is a way of propagating property values from parent elements to their children.

Some CSS properties are inherited by the children of elements by default. For example, if you set the body tag of a page to a specific font, that font will be inherited by other elements, such as headings and paragraphs, without you having to specifically write as much. This is the magic of inheritance at work.

The CSS specification determines whether each property is inherited by default or not. Not all properties are inherited, but you can force ones to be by using the inherit value.

3.1 Object-Oriented Programming Inheritance

Though beyond the scope of this article, CSS inheritance shouldn’t be confused with object-oriented programming (OOP) inheritance. Here is the definition of OOP inheritance from Wikipedia, and it makes clear that we are not talking about the same thing:

In object-oriented programming (OOP), inheritance is a way to form new classes […] using classes that have already been defined. Inheritance is employed to help reuse existing code with little or no modification. The new classes […] inherit attributes and behavior of the pre-existing classes. …

3.2 How Inheritance Works

When an element inherits a value from its parent, it is inheriting its computed value. What does this mean? Every CSS property goes through a four-step process when its value is being determined. Here’s an excerpt from the W3C specification:

The final value of a property is the result of a four-step calculation: the value is determined through specification (the “specified value”), then resolved into a value that is used for inheritance (the “computed value”), then converted into an absolute value if necessary (the “used value”), and finally transformed according to the limitations of the local environment (the “actual value”).

In other words:

1. Specified value
   The user agent determines whether the value of the property comes from a style sheet, is inherited or should take its initial value.
2. Computed value
   The specified value is resolved to a computed value and exists even when a property doesn’t apply. The document doesn’t have to be laid out for the computed value to be determined.
3. Used value
   The used value takes the computed value and resolves any dependencies that can only be calculated after the document has been laid out (like percentages).
4. Actual value
   This is the value used for the final rendering, after any approximations have been applied (for example, converting a decimal to an integer).

If you look at any CSS property’s specification, you will see that it defines its initial (or default) value, the elements it applies to, its inheritance status and its computed value (among others). For example, the background-color specification states the following:

Name: background-color
Value: <color>
Initial: transparent
Applies to: all elements
Inherited: no
Percentages: N/A
Media: visual
Computed value: the computed color(s)

Confusing? It can be. So, what do we need to understand from all this? And why is it relevant to inheritance?

Let’s go back to the first sentence of this section, which should make more sense now. When an element inherits a value from its parent, it inherits its computed value. Because the computed value exists even if it isn’t specified in the style sheet, a property can be inherited even then: the initial value will be used. So, you can make use of inheritance even if the parent doesn’t have a specified property.

3.3 Using Inheritance

The most important thing to know about inheritance is that it’s there and how it works. If you ignore the jargon, inheritance is actually very straightforward.

Imagine you had to specify the font-size or font-family of every element, instead of simply adding it to the body element? That would cumbersome, which is why inheritance is so helpful.

Don’t break it by using the universal selector (*) with properties that inherit by default. Bobby Jack wrote an interesting post about this on his Five-Minute Argument blog. You don’t have to remember all of the properties that inherit, but you will in time.

Rarely does a CSS-related article not bring some kind of bad news about Internet Explorer. This article is no exception. IE supports the inherit value only from version 8, except for the direction and visibility properties. Great.

4. Using Your Tools

If you use tools like Firebug or Safari’s Web Inspector, you can see how a given cascade works, which selectors have higher specificity and how inheritance is working on a particular element.

For example, here below is Firebug in action, inspecting an element on the page. You can see that some properties are overridden (i.e. crossed out) by other more specific rules:

Firebug in action, informing you how specificity is working.

In the next shot, Safari’s Web Inspector shows the computed values of an element. This way, you can see the values even though they haven’t been explicitly added to the style sheet:

With Safari’s Web Inspector (and Firebug), you can view the computed values of a particular element.

5. Conclusion

Hopefully this article has opened your eyes to (or has refreshed your knowledge of) CSS inheritance and specificity. We encourage you to read the articles cited below, as well as Smashing Magazine’s previous article on the topic.

Even if you don’t think about them, these issues are present in your daily work as a CSS author. Especially in the case of specificity, it’s important to know how they affect your style sheets and how to plan for them so that they cause only minimal (or no) problems.

You are not literally cropping, which is why it’s called faux image cropping. These techniques can be helpful if you want to keep images to a certain size (for example, thumbnails in a news section). Being able to use CSS to control which portion of an image to display is great.

Image Rollover Borders That Do Not Change Layout
With CSS, the border of any block-level element is factored into the element’s size in the layout. So, if you add a border to an element on hover, the layout will shift. In this post, you will find how to use the regular border property and create inner borders to get around that.

Horizontal Stripes
This tutorial shows you how to create never ending horizontal stripes in your web design using CSS.

Nine Techniques for CSS Image Replacement
Put nine different techniques of image replacement to the test.

Bokeh effects with CSS3 and jQuery
This tutorial teaches you how to re-create the bokeh effect with CSS 3. With some help from jQuery, we can add some randomness in colour, size and position for the effect.

A Stationary Logo That Changes on Page Scroll with CSS
Here is an interesting effect that modifies the logo when the page is scrolled, using the CSS background-attachment property.

Silhouette Fade-Ins
To achieve the effect in the image above, first we need a DIV with the silhouettes as a background image. Then we put four images in that DIV, all the exact same size, with each band member highlighted. These images are hidden by default. Then you absolutely position four regions on top of the DIV; these are the roll-over link areas. With jQuery, we apply hover events to them, fading in the appropriate image.

Creating Triangles in CSS
Few people realize that a browser draws borders at angles. This technique takes advantage of that. One side of the border is given the color of the arrow, and the rest are transparent. Then you give the border a large width; the ones above are 20 pixels.

A parallax optical illusion with CSS: The Horse in Motion
Time for some fun with CSS and optical illusions.

Pure CSS Line Graph
The idea here is not only to offer data visualization to people who aren’t comfortable using scripting languages, but to demonstrate the power of CSS and offer a different way of using CSS. If you are not a fan of line graphs and data visualization, you may still benefit from this article. Think of it as a CSS experiment, and learn a thing or two about CSS Sprites and positioning.

Zooming with jQuery and CSS
This post is about text zooming with jQuery and CSS. This is a basic-level tutorial about changing a style using a jQuery script. A simple way to zoom website content.

Create Resizing Thumbnails Using Overflow Property
This tutorial teaches you how to control thumbnail sizes. Sometimes we don’t have enough space to fit large thumbnails, and yet we would rather avoid small indecipherable images. Using this trick, we can limit the default dimensions of thumbnails and show them at full size when the user mouses over them.

Cross-browser drop shadows using pure CSS
Most methods of adding drop-shadows to content blocks require additional HTML mark-up and one or more PNG images. But by combining the Glow and Shadow filters, something that fairly closely resembles the rendered CSS3 shadow can be achieved.

Date Badges and Comment Bubbles for Your Blog
One of the things you have to deal with when your blog grows is having to cram more info into less space to show everything you want to show. One thing you can do is add an icon for the date and then a bubble over it with the number of comments for that post.

CSS Tables And Web Forms

UX trick: display form data as tabular data
This is a little trick to enhance the user experience of forms. It displays editable form data as readable tabular data.

Tables: Not As Evil As You Think
Tables are evil, right? Yes and no. For tabular data, they’re not, of course. That’s what tables are for in the first place. CSS can do an excellent job of styling a properly formatted table, and the table structure provides good scaffolding for JavaScript calls. But what is addressed here is using tables for non-tabular data (i.e. for the layout). Yes, that’s right: using tables for layout.

Perfect Drop-Down Log-In Box Like Twitter Using jQuery
This shows you how to create a Twitter-style drop-down log-in form using jQuery. It’s really easy, it saves space on the page and visitors feel comfortable with the awesome toggle form.

Make a Select’s Options Printable
When printing a Web page with select elements on it, the select drop-down prints just as it looks on the Web. This of course is practically useless on the printed page. One option for handling this is to follow every select HTML element with an unordered list that duplicates the content. Hide the unordered list in your main CSS file and reveal it with your print style sheet. This is a reasonable approach, except that it’s a big ol’ pain in the butt to deal with all the time. Let’s rely on jQuery to do the heavy lifting instead.

Twitter-Like Log-In With jQuery and CSS
This post explains how to get the Twitter-like hide and show effect for logging in using jQuery and CSS.” Very simple: just five lines of JavaScript for the hide() and show() events and a little CSS.

Clean and Pure CSS Form Design

How to Mask Passwords Like the iPhone
Many smartphones, including the iPhone, show the last character that you typed in a password field with a delay of a second or two. You can see that last character but not the entire password. But browsers don’t do what these mobile devices do. Here is a solution, with some fancy JavaScript and behind-the-scenes trickery.

Make Web Forms Suck Less With Labels
We’ve been filling out Web forms for years, and we all gripe that they could be better. Even with generous padding, the fields are too small. But hardly anyone has improved the most under-rated interaction of them all: checkboxes and radio buttons.

FancyForm: JavaScript checkbox replacement
FancyForm is a powerful and flexible checkbox-replacement script that changes the appearance and function of HTML form elements. It is accessible and easy to use, and it degrades gracefully on older non-supported browsers.

jQuery checkbox v.1.3.0 Beta 1
A lightweight custom-styled checkbox implementation for jQuery 1.2.x and 1.3.x.

Disabled labels and the Trilemma plug-in
The form above on the left makes use of the disabled attribute, but the default browser settings for disabled inputs don’t contrast as much as one would like. To better distinguish at a glance between which inputs are disabled and enabled, the labels of disabled inputs in the form on the right are styled with a faint gray color.

Fluid Search Box
Creating a fluid search box when you have only a single element next to it is trivial. What you should do is wrap the input in an element and use padding to create space for the fixed element; then position the fixed element absolutely (or relatively) in the space created by the padding.

Last Click

The short answer is “as much as you need”. The more tactical answer is “as much as you can raise cheaply”. The latter is a pragmatic view. Raise more than you need when times are good. Just because you raise it does not mean you need to spend it – capital efficiency is always good!

In this post I look at what VC are saying SaaS ventures need to raise to get to scale and profitability. But I’ll also look at what VC are doing – what SaaS deals they are funding currently. I look at the capital efficiency drivers, what you can do to reduce your need for capital. And finally, I show you which VC are active in SaaS today.

Sponsor

What Are VC Saying?

The answer according to Bruce Cleveland of Interwest is about $40m.

Take that seriously. Cleveland is a SaaS specialist with serious operational experience who has done his research on this subject. But as he points out, the details matter. There are two points of caution:

1. This is looking in the rear view mirror at ventures funded some time ago that did an IPO in 2007 or earlier. It is a different world today – less capital available and less need for capital.
2. VC are happy with models that require a lot of capital. Capital is what they have to offer and if you need a lot they are in the driving seat.

Lets look at the operational details, the capital efficiency drivers, in a minute. First, lets see what VC are actually funding today.

What Are VC Doing?

We looked at the Series A round for 17 SaaS ventures that closed after January 2007:

• Clarizen
• Maxplore
• Loopfuse
• Jive Software
• SlideRocket
• Elastra
• Syncplicity
• SocialCast
• AriaSystems
• Lavante
• Lithium Technologies
• Maxplore
• PivotLink
• SmartTurn
• Zuberance
• InsideView
• Bill.com

These 17 ventures raised $90.25 million total, an average of $5.3 million. That sounds like the “old normal” $5 million Series A. You can see how you would get to $40 million for a venture that is getting traction and can do a series of larger rounds at higher valuations. Lets say, a) $5 million; b) $10 million; c) $25 million; and total: $40m.

If the C round is pre IPO, everybody does well. But that is the old normal. The new normal is different. First, those 17 deals had two outliers: Jive raised $15 million and Bill.com raised $17 million.

Now let’s start with a later date. If we filter by Series A deals that were done after the market meltdown in Q4 2008, the average more than halves to $2.55 million. Those five deals are:

• Maxplore
• Loopfuse
• Syncplicity
• Zuberance
• SocialCast

Capital Efficiency Drivers

There are two numbers to obsess over.

1. How much does it cost to acquire customers? Cleveland defines this as CAC/ACV, or Customer Acquisition Cost divided by Annual Contract Value. If this is less than one you are in good shape. You can take this further. If you can get your customers to pre-pay for the year and your CAC/ACV is less than one, you can self-finance growth at least on the marketing side. Charging annually rather than monthly will slow down growth but that would be a small price to pay for controlling your own destiny. In some markets, customers will pre-pay in return for a discount and that is certainly the cheapest capital you will ever get.

2. How much do you need to spend per customer on infrastructure? The SaaS pioneers made a big play out of having their own data centers. When SaaS/Cloud was new, this was essential. Today you will be courted by lots of big, deep-pocketed, credible cloud vendors selling PaaS, IaaS and HaaS on a pay-as-you-go basis. The pay-as-you-go basis means you don’t spend precious capex on infrastrucure.

But more important is the total ICC or Infrastructure Cost per Customer. If this is low enough you can afford to be more creative with your freemium strategies – which will reduce your CAC/ACV if done right. In other words, your R&D guys had better pay attention to performance engineering from the get go. The days of throwing sloppy code out there and covering your mistakes with huge dollops of cash later are probably over.

Who You Gonna Call? SaaS Funders!

You need capital to build a SaaS venture. You can self-finance using the cash flow from another business. (Typically a professional services business as this requires no capital.) This is what both 37 Signals and Zoho/Advent did. But that is still capital, it is just your own capital!

If you have a small niche, you might need very little capital as it is easy to reach your market. Which is a good thing as no VC will fund a small niche. If you are have a venture that is in that rare magic quadrant that is both viral and monetizable… well you are one lucky dude!

For SaaS ventures that are going after a big market and have normal marketing characteristics, VC (probably preceded by Angel) is the conventional route. If you do decide to raise VC for your SaaS venture, it is better to go to a SaaS specialist.

We know this is not an exhaustive list. It is not meant to be. We have seen many VCs do one or two SaaS deals. We want to highlight the VCs that have done more than that, and that have an active focus on SaaS (a section on their site, a partner focused on SaaS, some interesting research, etc.). These are the ones that made that cut:

• Bay Partners
• Benchmark
• Bessemer
• Emergence
• HummerWinblad
• Interwest
• Northbridge
• TrueVentures
• Venrock

What you really need to know is, who is funding SaaS ventures right now. Here is the much shorter list of VC that have done two or more SaaS A Series deals since the start of 2007:

• Emergence
• TrueVentures
• HummerWinblad
• Venrock

OK, let’s make a really fine filter. Who has done SaaS A Series deals since the market meltdown in Q4 2008? That list is down to two firms:

• Emergence
• TrueVentures

In raising money, relationships matter – a lot. So if you know a VC that is not yet active in SaaS, call them. If your venture puts them on the SaaS map, they will love you. For most VC that like Internet or software like SaaS, the business model attractions are screamingly obvious.

CSS Navigation Menus

CSS 3D Meninas
“I’ve took the classic paint The Maids of Honour (Las Meninas) and created a CSS pseudo-3D / Parallax effect. It is pure CSS, no JavaScript or Flash is involved. It has been tested and is working on Internet Explorer 8, Firefox 3, Opera 9, Safari 3, Chrome 4 and Konqueror 3.5, and it validates, too.

How to Create Simple and Effective Sub Navs with Definition Lists
“When we need simple and effective on-page navigation, to either jump to content on the page or flip to another view, we use the dl element. Its sub elements, the dt and dd, make it very easy for us to create inline links with a clear label. Here we’re going to share with you a fast, lightweight method for how we’ll use CSS to do it.”

Sticky SideNav Layout with CSS
Learn how to create a fixed sidenav layout for your blog or website. Having a fixed sidenav comes in handy when dealing with blog style websites where the content is extremely tall and there is a need for good amount of scrolling. The fixed navigation allows the user to cruise through the content without scrolling back up to the top to navigate through the rest of the site.

Unobtrusive Dropdown Page Changer
Using a <select> dropdown menu to create navigation isn’t as common as it once was, but it’s still around. It got ripped on pretty good for being an inaccessible / obtrusive. Indeed a lot of the scripts you’ll find out there for creating a menu like this are this way. Bummer. Let’s make one that works with or without JavaScript.

CSS Navigation: No JavaScript, jQuery or Image Required, Free CSS Navigation / Pagination with Tooltip
CSS-based navigation / pagination bar without JavaScript. There is a tooltip on hover for the ‘previous’ and ‘next’ page’s bullets that makes navigation easier.

How to Code an Overlapping Tabbed Main Menu
Main navigation menu is that part of a website design that makes the whole site look lively and complete. But the most common type of navigation menu style still being used a lot is the tabbed navigation menu. Here is a tutorial on how to code an overlapping tabbed menu.

Solution For Very Long Dropdown Menus
“I like to be confident with post titles, but the reality in this case is a possible solution for very long dropdowns. The problem with long dropdowns is that the dropdown itself can go below the “fold” of the website. That is, below the visible area of the browser window. So in order to access those menu items down below, you need to scroll your browser window. For those of us with scroll wheels of some kind on our mice (mouses?), it’s not a big deal. For those without, those lower menu items are totally inaccessible, because to use the browser scrollbar means mousing off the menu (and probably having it close).”

Mega Drop Down Menu w/ CSS & jQuery
When used properly, mega drop down menus can be quite efficient for large scale websites. Let’s experiment with different ways of implementing this technique. A tutorial by Soh Tanaka, Smashing Magazine’s regular author.

CSS Typography and Body Copy

How to Create a Cool Anaglyphic Text Effect with CSS
Anaglyphs are those amazing 3D images that are created by offsetting two of the red, green and blue channels, and are viewed with those nerdy looking 3D glasses with different coloured lenses. I don’t know if this effect works for real, as I’ve unfortunately misplaced my 3D specs, but it’s a pretty cool text effect nevertheless! Let’s take a look at how a similar style can be created for sprucing up your web designs, while taking into consideration semantics and avoiding the repetition of any markup.

Typographic work planner
Enter this, a little HTML/CSS typographic work planner. By using some super-semantic HTML and a dash of CSS you can craft a beautiful looking yet incredibly simple work planner for you and your staff.

Thinning Text in Webkit (Safari)
Safari has a not-so-lovely way of bulking up text using sub-pixel rendering. On previous versions of Safari, this was fixed with a text-shadow declaration, but since Snow Leopard that method no longer works. Fortunately, there is an alternative.

Pseudo Drop Caps
They’ve been around for a while now, appearing in magazines, print and now the web. Designers and developers alike have experimented with multiple workarounds from using inline styles to using image replacement but with both of these solutions there are problems. For example, what happens when you recreate your site and decide that you no longer want to upload the drop cap images, you’re now going to left with a broken image at the start of every single post that you had previously created, this is obviously assuming you haven’t used text-indent. If you decided to go down on the inline style route then your are just bad, just very bad.

How to Create Perfect Pre Tags
If you operate a website that features lots of code examples, you know how important it is to spend some quality time styling the &tl;pre> element. When left unstyled, wild <pre> tags will mangle your preformatted content and destroy your site’s layout. Different browsers treat the <pre> tag quite differently, varying greatly in their default handling of font-sizing, scrollbar-rendering, and word-wrapping. Indeed, getting your preformatted code to look consistent, usable, and stylish across browsers is no easy task, but it certainly can be done. This article explains everything you need to create proper <pre> tags.

Improve your web typography with baseline shift
The baseline is an invisible line onto which all type characters sit, although of course some characters (including ‘j’, ‘p’, ‘g’ and ‘y’) have descenders that hang below the baseline. Baseline shift involves moving characters up or down in relation to the baseline and using it effectively can make a huge difference to the professional look of your type. Although baseline shift has traditionally been a part of using tools like InDesign or Quark, there are ways to accomplish the same results using CSS.

Typograph – Scale & Rhythm
This page is both an essay and a tool. It sets out to explore how two, intertwined concepts, often playful but sometimes cheeky, can be encouraged to dance in web pages. Drag the colored boxes along the scale to throw these words anew. For the most part, this text is just a libretto for the performance you are about to play upon it.

How To Create Simple, Stylish and Swappable Image Captions
Most image caption solutions require a lot of excessive HTML, make it difficult to redesign or don’t communicate clearly that they belong to an image. Let’s see what we can do to address these problems.

Styling photo captions with CSS
Sure, some photos are self-explanatory, but most photos are best served with text captions. It’s true for traditional media like newspapers and magazines, and just as true for blog posts and web articles. Here’s a quick tip on using photo captions and styling them nicely with the magic of CSS.

Image captions on Web pages
This document suggests three ways of presenting an image with a caption in HTML. Styling in CSS is also discussed.

Styling Post Headings That Stick Out
“Recently, I’ve noticed a trend in blog post headings where it sticks out of its base layout. I would like to share this technique for those who would like to give their post headings a new style. One tip to keep in mind when designing this is to make sure it fits your target audience screen resolution size. Note that this technique may vary depending on your design. My goal is for you to grasp the main concept in this tutorial so you can experiment and apply it to your own projects.”

Using ellipsis with HTML and CSS
If the text is too wide to fit into a container, a nice solution can be to have ellipsis to show there’s more information available. While not currently part of the official HTML specifications, it is possible to have ellipsis defined in CSS and it works for Internet Explorer, Safari, Chrome and Opera. It doesn’t work for Firefox but there’s a workaround that can be done with jQuery.

CSS Lists

Create a Microsoft Word-Style Outline with CSS
As you can see, the browser doesn’t bother to vary the indentation style much, or change the list type from roman numerals to alphabetical characters and so on… all the things we’re so used to seeing because Microsoft Word and other writing programs do them by default. So let’s use a bit of CSS ingenuity to make a Microsoft Word-styled outline using ordered lists!

Pure CSS Timeline
“I wanted to build a CSS timeline for the “About” section of my site while using some clean and simple markup. I wanted to avoid using images as much as possible, so I spent a few minutes prototyping some options and came up with a solution using unordered lists. The result is a simple and clean looking timeline with some very straight forward markup. In this article I’ll share my approach to creating a timeline out of CSS and HTML which results in a nice looking, simple timeline.”

Automatic numbering with CSS Counters
When writing documents, it is often useful to number sections and have a table of contents. You can number these by hand, directly in the markup, but this can be time consuming if the order changes and you have to edit all the numbers. CSS2.1 gives us a automated way to generate numbers using CSS counters, and this article will walk you through how to use them. One word of note before we start is that CSS counters are not yet implemented in IE, although they are on the roadmap for IE8.

CSS tricks for custom bullets

Elastic Calendar Styling with CSS
A traditional calendar is a grid of numbered boxes on a page. As a web designer, you might go right for a table, and I wouldn’t fault you for that. Tables, though, can sometimes be tough to muscle into shape. The CSS purist in me gets pissed when I set the width of a table (or a cell) and it decides it knows better and grows or shrinks as it sees fit.
You can tackle calendar styling with pure CSS, and I feel it makes just as much sense semantically as a table does. What is a calender, if not an ordered list of days? By using CSS, we can even do some cool things like do all our sizing with ems so our calendar layout will be elastic. That is, grow in both width and height when text is resized in browsers, while greatly increasing accessibility.

Style a List with One Pixel
A one-pixel background image can be a pretty versatile thing. With repeat-x it can be a horizontal line, repeat-y makes a vertical line, and repeat makes it a fill color. Just as a little fun proof of concept, we can use that to create a depth-chart looking unordered list.

Style Your Ordered List
By default, most browsers display the ordered list numbers same font style as the body text. Here is a quick CSS tutorial on how you can use the ordered list (ol) and paragraph (p) element to design a stylish numbered list.

Simulating a Table Using an Unordered List
Your first question immediately might be, “why would I want to simulate a table with a list, why not just use a table?” With the raise in popularity of AJAX sortable list elements, using list items to represent a multiple column data table can allow for easy sorting of various more “tabley” information. So let’s get started.

8 different ways to beautifully style your HTML lists with CSS
“The use of HTML lists (<ol> for an ordered list, <ul> for an unordered list) is very common these days. Today, we’re going to look a little bit further than creating regular lists, by showing 8 different ways to beautifully style your HTML lists with CSS. We’ll use some pure CSS techniques to make a bored list look awesome (and even have some extra functionality).”

Quick Tip – Simplify List Margins with CSS
Have you ever set default margins for a layout, and then had to go back and manually adjust all of your lists? By default, list item markers have a negative positioning in relationship to the list item itself. This means that zero-ing out margins automatically leads to an overflow if the list is contained inside anything else. Wouldn’t it be easier to put the list item marker at the same starting point as other elements instead? Lucky for us, there’s a style to help do just that. Let’s see what can be done with the list-style-position property.

Sexy HTML List Tricks
Behold the ubiquitous list elements, <ul> and <ol>. These two sexy elements help millions of websites display lists of information in clean, semantic fashion. Without them, we’d be crawling around like filthy cavemen, eating dirt and howling at the moon. But these list elements aren’t just sexy, they are also extremely flexible, enabling us humble designers to create robust list configurations that are semantically versatile and highly customizable.

Clickable <li>
I originally coded the markup to be a table, but discovered a problem when I tried to make the whole row clickable. I ended up with a list of articles instead.

CSS Buttons

Simply-Buttons v2
This technique presents buttons of the size that always fits the content. There are 3 states: inactive, active and hover. The technique works in all major browsers and doesn’t require JavaScript.

How to make sexy buttons with CSS
This tutorial will teach you how to create pretty looking textual buttons (with alternate pressed state) using CSS. Dynamic buttons save you heaps of time otherwise spent creating graphics and will basically make you a happier person at the end of the day.

Liquid & Color Adjustable CSS Buttons
When working on a large site with multiple buttons, it can be quite tedious to make all the buttons in Photoshop. Making future adjustments on the verbiage and colors can be also be time consuming. By having dynamic buttons, this scenario is much easier to handle, and by having liquid and color adjustable buttons with CSS, we are able to change the verbiage and colors in a flash.

Create a Button with Hover and Active States using CSS Sprites
Too many designers neglect the click state (active-property in CSS) in web design, either because they’re unaware of it, underestimate the importance of it or are plain lazy. It’s a simple effect that improves usability by giving the user some feedback as to what they’ve clicked on but can also add depth to a design.

Recreating the button
“I thought it would be interesting to provide a portion of the background on buttons here, and discuss some of the iterations we’ve been through so far to get to the current state.”

Rounded form buttons

For example, our F-MyLife application leverages multiple ad networks to fill it’s inventory. It currently uses the AdWhirl SDK to do this and it worked great for a while; however, our buddies over at MobClix built a much better ad aggregation platform with far more networks and we’ve since moved most of our traffic to MobClix so they can manage it. Since the AppStore is a pain in the ass and getting an update out would have taken weeks, we were able to allocate all of our traffic to MobClix via AdWhirl and MobClix’s new platform was able to handle everything from there. We ran our ads like this for over a month and then we started noticing a dropoff in our revenue. We scrambled to find out what the problem was, but since we were filtering through data from multiple networks, it was nearly impossible to put two and two together.

We decided that in order to analyze all of this data and really see connections between everything, we were going to need to build something. So Shaun spent a few nights working on a web application that pulled in all of our data from all of our networks so it could be analyzed and displayed in a readable format along with some charts. This was a huge life saver. After reviewing the reports that we built for ourselves, we noticed a huge problem with our click-through rates and began working with everyone to resolve them.

Had we not built this tool, we probably would of never known the real cause of the issue. In fact, had we built this tool a month ago, we would of identified the bug earlier and we could have fixed it.

You don't always need to "roll your own solution" though. There are tons of products and services out there designed to fix problems just like yours, you just need to research them and set them up. A similar scenario occurred with our servers. We run FML/TWI & ProTip on Amazon's EC2 infrastructure and we monitor everything with Pingdom. The other night, we had a 6 hour downtime between 2am EDT and 8am EDT. The problem was remedied by a simple lighttpd restart; however, during that time, we lost a lot of revenue. This wasn’t the first time that this happened either! So, yesterday, we setup Scoutapp to keep an eye on our server load and monitor some other metrics (like MySQL). When we woke up, we were greeted with a bunch of alerts from Scoutapp telling us that we had 1 SQL query which was taking an awfully long time to run and bogging down the server. We logged in, identified the query, figured out why it was taking so long to run and remedied the problem by adding an index to one of our tables. Done!

If it weren’t for Scoutapp, we would of had to manually log into each server, every morning and manually check the slow query logs. This is painstaking and given that we’re a small company with hundreds of things in the works at any given time, we don’t have the free time available to check logs. Scoutapp saw a problem, let us know about it, and we fixed it. A tool saved our ass yet again.

This happens over and over in the software development business. After you’re done with the product, and it makes you a little bit of money, you NEED to build or setup tools that can help you manage your new business. If you don’t, you’ll spend all of your time managing your first product instead of working on your next.

Heartbeat was the first tool we built to manage our AppStore products. It’s been a great asset to us and after having had over a year of experience on the AppStore, we’re working on Heartbeat 3.0 which will incorporate all of the knowledge that we’ve gained through the past year.

It seems counter-productive when you’re a small company, but that’s when these little things help the most. You don’t have the time to do it all, so it’s important to automate as much of your business as possible. Services like Pingdom and Scoutapp have helped us maintain uptime on our servers. Others like Sifter and Tender have helped us keep track of bugs and deal with support issues from our customers.

There are a ton of other products and services out there that can help you run your business. If you can’t find one to meet your specific needs, spend some time, and build your own. Trust me, you’ll thank yourself in the long run.

Did you know that this kind of thing was even possible? The video shows Danny MacAskill. who rides for UK trials bike company Inspired Bicycles, shredding it in Edinburgh. As our own Danny Dumas says on Twitter*, “From what I gather this is parkour…done with bicycles.”

Keep watching. If you think it’s all over after the first couple of minutes, it isn’t. The video just gets bigger and better as it goes on.

*Normally, of course, Danny’s answer to the Twitter question “What are you doing?” is “Styling my hair. My beautiful hair. In the mirror.”

If you’re still skittish about being locked in for a lengthy contract and don’t mind the fact that new hardware will almost undoubtedly be hitting the streets in only a couple of short months, and if you have money lying around not doing anything useful, Buy.com has a deal for you, for the low price of $799. That’s the price you’ll pay for a brand-new, in-box, unlocked Apple iPhone from Buy.com. In fact, it’s better than unlocked, it’s never been locked in the first place, so you won’t have to worry about sketchy jailbreaking/unofficial unlocking procedures if you’re not tech-savvy.

The never-locked 16GB iPhone 3G comes with a full Apple warranty, which is probably not the case with most unlocked units you’ll find on eBay, but Buy.com does warn that you might not be able to understand your product’s instruction manual, since the devices come from all over the world, and not necessarily English-speaking countries. That means this is probably a case of an overstock buy-out from a variety of global carriers in preparation for the June WWDC ‘09 iPhone hardware refresh.

Apparently you can easily swap out SIM cards using these models, so if you’re a globetrotter, this might just answer your prayers. And maybe Om Malik, over at our sister site GigaOM, can finally come back to the iPhone fold using a more dependable network than AT&T’s.  T-Mobile, or any of the 30 different smaller GSM carriers in the U.S., will work with these phones out of the box, according to Buy.com’s product information site. Plus, unlike with unofficially unlocked phones, you can connect to iTunes and update without worrying about being locked out and having to jailbreak again.

I’ve been wanting a second device so that I can devote one to testing, and it’d be nice to have something I can travel with and use pay-as-you-go SIMs with so as not to get charged massive roaming fees, but my heart flutters every time I think about that $799 price tag. Plus, I’m already going to be sufficiently gouged when the new iPhone hardware comes out in June and I have to try to talk my carrier into allowing me an upgrade when I still have two years left on my contract.

Buy.com may just be trying to move more units, but they are claiming that they have very few units left in stock. Anyone planning on picking one of these up? If so, what for? Is the $799 price justified, considering the freedom you get by avoiding a contract/AT&T’s spotty network?
