Advantages of standards

Possibilities of standards

A common misconception is that websites compliant to standards are dull, poorly designed and not eye-candy. That's completely wrong. The standards support a wide range of possibilites that match the most advanced HTML or JavaScript code. Just have a look at those links for examples:

Why would people not just use the same browser? It'd fix problems

There's many reasons why people don't use the same program to achieve the same task. Those reasons are pretty much the same as why we are not all dressed the same way or don't own the same brand and model of cars.

Create your own site: the basic tips

If you plan to write a new site from scratch, then it is highly adviced to use XHTML to write it. Don't be afraid, XHTML is pretty close to traditional HTML except on some major points.

First, in XHTML, the layout & style are separeted from the content. Basically, XHTML pages only stored the content of your site and the style is stored in CSS pages. This means you should not use any <font> tags for text rendering and avoid using tables for the layout.

The other main difference with HTML is that tags are case-sensitive and must be written in lower case (<strong> is correct, <STRONG> is not). Also, each tag opened must be closed (<p></p> is correct, <p> is not).

Tutorials about XHTML and CSS are available at Practical CSS examples are available at, and (in French).

XHTML and CSS are not a problem for old browsers. The code they don't understand will simply be ignored and won't cause troubles accessing the site. Only the layout/design may be altered, but the site's content stays fully readable.

P.S.: don't lose your time with Internet Explorer 4 and Netscape 4 browsers, they're not conform at all, and should be forgotten forever.
