list-style-type | NN 4 IE 4 CSS 1
| Inherited: Yes
Sets the kind of item marker to be displayed with each item. This attribute applies only if list-style-image is none (or not specified). The constant values available for this attribute are divided into two categories. One set is used with ul elements to present a filled disc, an empty circle, or a filled square (except on Version 4 browsers for the Macintosh); the other set is for ol elements, which have list items that can be marked in sequences of Arabic numerals, Roman numerals (uppercase or lowercase), or letters of the alphabet (uppercase or lowercase), and some other character sequences of other languages if the browser and operating system supports those languages.
