The <UL> tag is one that lists items in an unordered fashion through means of bullets. Bullets are simple dots in front of text and / or links if you choose to do so.
 Although this tag is limited to text, you are able to include links and also size and color when you use the font tag.
 If you are not careful this tag can make your documents quite ugly so be careful and your visitors will appreciate the fact that you have went to the length to make them comfortable and satisfied that you organized the data so they can get it and go.
 The <LU> tag requites that you close your statement with the </LU> tag and requires that you use the <LI> tag between the two. The <LI> tag stands for List Item and does not require that you close it out but you must use the tag in from of every item you want to list.
