What is CSS and why would I want to use it?
CSS is an acronyn for Cascading Style Sheets. Style Sheets allow you to easily change the layout of a page while maintaining the content. Styles can be written directly into your HTML files, or managed in a separate .css file. For an excellent example of what you can do with CSS check out the CSS Zen Garden at http://csszengarden.com. Zen Garden uses CSS to create new themes and visuals though the text content remains unchanged.
