Lists are just a way to display information and html has some built in mechanisms to work with them. You have unordered and ordered lists. The first just using bullets and the latter using numbers.
The tags are <ul> for an unordered list and <ol> for an ordered list. With the container <li> to show information that will go after each bullet or number. Example :
CODE
<ol>
<li> information </li>
<li> information </li>
<ul>
<li>more info </li>
<li>more info </li>
</ul>
<li> information </li>
</ol>
Notice I nested some lists in there just to see how you could possibly use them.
Now , if you have read through all the Guides to the Web that I have posted, go ahead and combine all of this information together and you can build yourself a couple pages that link between each other and display both graphics and text. Think of an idea , just something simple that would require a few pages to build a website for. Make up a company and have an about page, news page etc.... and just type out some html. The best way to learn this stuff is by playing with it and getting everything down pat.
