Have you been hearing about using CSS (cascading stylesheets) and wondered just what is that? and why would I want it?
For an idea of just what is possible with CSS, check out CSSZengarden. The game here folks is this: there is an html file, all tagged up neatly so that it validates and is accessible and all that good stuff. And, the designer gets to make it look like whatever he/she wants visually using css ( a separate file that is linked to the html). No javascript or any programmer stuff like that. Just styles (which include graphic images) and the original markup. As you flip through the site take not of the fact that the content on every page is identical - just displayed in different ways.
Now - if that doesn’t get you interested I just about give up… but I would recommend that you do learn about style sheet basics. Like, how to make it easy to get all of your titles to display in the same font, size, color and alignment without using the accursed tag. Go forth and learn!
