you use the CSS attribute "list-style: square" on the UL tag (either by inserting the code into your CSS stylesheet or by appending style="list-style: square" to your UL tag)
You can make a list that has numbered items in HTML by using the Ordered List tag. The syntax for this tag is exactly the same as it is for an unordered list, except you'll use <ol> instead of...
Like this:
<ul>
<li>first entry
<li>second entry
<li>...
</ul>
'ul' is 'unordered list', using bullet points. 'li' is an item in the list.
