In other words, the Web Inspector tool is nothing but an intricate, sophisticated, and extremely well designed web page!
Having built a Crystal Black CSS file for web pages in general, and with my past expertise in CSS, I attacked this challenge with relish! It reminded me of the time I realized that Dashboard widgets are, at their core, nothing but little web pages (as are simply apps for the iPhone). In tackling this one, the main question was, How should the various elements look? And the hardest part was inspecting the various parts in of the Inspector in great detail to determine which CSS rules governed their default appearance and behavior.
As I discovered, the WebKit has a a sub-framework called "WebCore," which in turn has a folder of resources specifically for the Web Inspector. In the Inspector folder, among other things, is a suite of CSS files that handle different aspects of the Inspector's design and behavior. Of these, the primary one I needed to tweak was called simply "inspector.css."

technique with the letter-soup name "XMLHttpRequest," became known as "Ajax." Ajax spawned an avalanche of cool, useful, and powerful new web applications that are today beginning to successfully challenge traditional computer-desktop software like Microsoft Word and Excel. As good as vanguard products like Goodle's Maps, Gmail, Documents, and Calendar apps are, one only has to peek at what Apple has accomplished with its new MobileMe web apps to see how much like desktop applications web software can be in 2008.
That this overwhelming trend toward advanced, desktop-like applications has happened at all is the result of the efforts of determined developers from the Mozilla project, which rose from the ashes of Netscape's demise to create the small, light, powerful and popular Firefox browser. The activity of the Mozilla group spurred innovation from other browser makers and eventually forced a trend towards open standards that made the emergence of Ajax possible.
This article starts with a brief history of web browsers and then jumps into a look at the feature set of the four primary "modern" web browsers in 2008. The comparison of browser features begins by listing the core features that all these browsers have in common. The bulk of the article lists in detail "special features" of each browser and each browser's good and bad points, as they relate to the core browser characteristics. Following that, I present some recent data on the comparative performance of these browsers. The article concludes with recommendations I would make to organizations interested in making the switch from IE6 in 2008.

This is an update to the article I wrote last summer, when Safari 3.0 was first released. In the 9 months since then, a lot has happened, and I wanted to try to keep this info up to date. Opera, iCab, Konqueror, and Firefox have all made progress in adopting CSS 3.0 specifications, the next generation of the W3C's Cascading Style Sheets standard.However, the WebKit team continues to lead the pack, as they have since I first contemplated this article over a year ago. In the last 6 months, that team has not only adopted more of the CSS 3.0 specs ahead of the others, but they have proposed several exciting new specs of their own, which the W3C is taking up as draft recommendations.
In addition to updating the state of CSS 3.0 in WebKit/Safari, I've also added some new demos for the Backgrounds section.
Here are the CSS 3.0 features I wrote about in July 2007:
- Box-shadow: Yes! Add drop shadows through CSS!
- Multi-column layout: Can we really do this now? With HTML?
- Resize: Give JavaScript hacks a rest and let users relax when typing input on web pages.
- Rounded corners: Any can be made round.
- Colors with transparency: There goes another ugly hack from way back!
- Background image controls: Remember how great it was when you could add images as well as colors to an element's background CSS style? Well, it's about to get a whole lot better!
And since then, WebKit and Safari 3.1 have adopted the following new ones:
- Adopted last October, WebKit introduced its first take at CSS Transforms, which it has submitted to the W3C for consideration. With CSS Transforms,
<DIV>s can be scaled, rotated, skewed and translated... all without using JavaScript! - Announced at the same time is the equally exciting implementation of CSS Animations. At the moment, the only type of animation that's documented and demonstrated on the WebKit blog is based on CSS Transitions, which let you define how an object or attribute changes over time from one state to another.
- Also in October, WebKit added the CSS Web Fonts feature, which lets designers beam fonts to users through CSS and HTML, approximating the capabilities of PDF in a much lighter-weight form.
- Then, after a lull, things started to heat up again last month, when Apple released Safari 3.1. Safari 3.1 incorporated all of the CSS 3.0 features WebKit had pioneered earlier, plus it added a bunch of things the WebKit team hadn't blogged about. Chief among these was support for CSS Attribute Selectors. This is something of a holy grail to advanced web developers, since it opens up a whole world of possibilities for using the Document Object Model (DOM) to build better web interfaces. When released, WebKit was the first and only browser to support this geeky, but highly practical feature.
- And then, just today, WebKit added support for CSS Gradients to its portfolio. Gradients are not yet a CSS 3.0 specification, but they are part of the HTML 5.0 spec. No doubt Apple's implementation will be referred to the W3C for consideration.
