"If you've never seen a website, you are a liar! (You're on one right now.) Consciously or not, the first thing you notice when you visit a website is how the site LOOKS, which is controlled by the CSS Stylesheet. CSS is the fashion of the web- it makes sites pretty (or very very ugly). And as our lives migrate more and more onto the world wide web, our presence online becomes a central way to define and express ourselves. So before you lay out your outfit for tomorrow, take a look at your website and make sure you match!"
