Sytlesheets are cool

Stylesheets are real easy to use. They are used to change the way standard HTML tags for. For instance, this page has a STYLE for the BODY tag. The BODY tag is this:
body {
	background: #ddadfd;
	margin: 2px 2px; color: green;
	font-family: Geneva, Arial, sans-serif; font-size:14px;
}
See how the back has the background color of ddadfd (purple), the text here is green, and the font type is 'Geneva, Arial, sans-serif'.

The box with the yellow background was made by assigning the InfoForYou class to the <pre class=InfoForYou> tag.

.InfoForYou {
    background: #edfd4e;
    border: 1px dashed green;
    color: #00F;
    padding: 2px;
    }

CSS Zen Garden is a great place to see what Stylesheets can do.
