Web Standards

Microsoft Internet Explorer you would expect would be the best but that is not the case. It is the most web standards complient browser but even though that is a case, people wont use it. There are other browsers that are good at interpreting CSS like the latest versions of Firefox and Opera on pc. Microsoft Internet Explorer 7 came out in 2006 and made major improvments over Internet Explorer 6 but the old version was still used by 50% of web surfers in 2007.
The Times They are A-Changing
Designers are moving away from using tables to lay out out their pages and using clean structual mark up. They stopped using certain commands to just force things to go where they wanted with no respect of the content that they are working on. Before web standards were layed out, most of the essential code was only roughly 25% in the example they showed with the other 75% just being filler.
XHTML and How To Write It
CSS is the main way that you style XHTML and if you dont have a solid understanding of XHTML, then using CSS with be dificult. XML has been universally adopted in business and the X in XHTML emphasizes the unstoppable movement toward the serperation of presentation and content. Since it keeps developing, XHTML will get replaced by another iteration of itself and be able to get expanded and can be shared in real time web services between other data systems.
