The style tag specifies a CSS style sheet. It must be placed within the head of the document.

Stylesheets here differ from those used in HTML in a few important ways.

The only type supported is CSS stylesheets. Javascript stylesheets are not permitted
The Style tag must not be enclosed in HTML comments ( <!-- --!>), in the way that is sometimes recommended for HTML

External stylesheets are linked via the link element.

These are some of the styles defined in the default stylesheet

<style>
b     { font-weight:bold }
i     { font-style:italic }
u     { text-decoration:underline }
o     { font-style:outline; outline-width:0.5 }
tt    { font:Courier }
</style>
