id's
id's are used in basically the same way, except they are preceded by a # instead of a full stop. As with classes, once you have defined an id you can associate it to any html tag as below.
<html>
<style type='text/css'>
<!--
#alison { color: yellow; background-color: blue; font-family: comic sans ms }
-->
</style>
<body bgcolor=black>
<p id="alison">This is a paragraph in a document using the id alison.</p>
</body>
</html>
There are several tags and properties that haven't been mentioned in this tutorial because they don't appear to have been implemented yet. As things change i will be adding more details.
