What Is CSS? CSS (cascading stylesheets) is a simple mechanism for controlling the style of a web document without compromising its structure. By separating visual design elements (fonts, colors, margins, and so on) from the structural logic of a web page, CSS gives designers the control they crave without sacrificing the integrity of the data, thus maintaining its usability in multiple environments. In addition, defining typographic design and page layout from within a single, distinct block of code — without having to resort to image maps, <font> tags, tables, and spacer GIFs — allows for faster downloads, streamlined site maintenance, and instantaneous global control of design attributes across multiple pages. Client-side support for the various CSS properties is uneven, even among browsers that support stylesheets. <p style="text-align:right;color:#A8A8A8"></p>
To make special characters and accented letters show up on your pages, use a special set of codes called character entities, which you insert into your HTML code and which your browser will display as the corresponding symbols or characters you want. The most common character entities have been collected by the International Organization for Standardization and compiled in the ISO Latin Alphabet No. 1 table, which includes special characters, letters with diacritical marks (accents, umlauts, etc.), and scientific and currency symbols. The Latin-1 table contains 255 characters. ISO Entities
Keep this cheatsheet handy — it contains the most common HTML tags and their proper syntax.

If you run a site on a Linux Web server, you may be spreading some proprietary software where you least expect it: in your site's fonts. Worse still, you're unnecessarily limiting your design to a pretty restrictive set of typefaces that are only widespread because everybody else uses them. Luckily it's a simple problem to fix. This weekend, you can wave goodbye to bland choices like Helvetica and show off some quality open source fonts all in one move. Don't believe it? Try this simple experiment.
Firefox 4 will come with better support for HTML5 forms. In the latest beta we are experimenting with a set of new features: more inputs types (email, url, tel, search), new attributes (placeholder, autofocus, list), decoupled forms and different validation mechanisms. This is thanks mostly to the hard work of Mounir Lamouri. Some examples will work in other browsers, but you’ll need Firefox 4 beta to see all of them. New input field types In the same fashion as new HTML5 elements, we have new field types to better express what kind of input we want.
"404 Not Found." These three little words can make any Internet explorer an unhappy camper. After all, who hopes to click on a broken link or stumble upon a moved or deleted page while cruising around the web?
