Lists come in two basic flavors in CSS: unordered and ordered. However, CSS allows for further customizations of lists, as compared to HTML, with the allowance for images to be used as the bullets in an unordered lists.

CSS List Style Type
If you are wanting to use something different then the default numbering of ordered lists, or the bullets/discs of unordered lists, then all you have to do is choose a different style for your lists. CSS allows you to select from a wide variety of differet list item shapes.

Unordered list styles: square, circle, disc(default), and none
Ordered list styles: upper-alpha, lower-alpha, upper-roman, lower-roman, decimal(default), and none
CSS Code:
ol { list-style-type: upper-roman; }
ul { list-style-type: circle; }
Display:
Here is an ordered list:

This list is
using roman
numerals
with CSS!
and now an unordered list:
This list is
using circle types
with CSS!
CSS Lists With Images
As we stated in the introduction, CSS lists allow you to insert an image in place of the normal bullets. A good choice for a bullet image would one that is smaller than the height of your text and is a relatively simple/plain graphic.

CSS Code:
ul { list-style-image: url("listArrow.gif"); }
ol { list-style-image: url("listArrow2.gif"); }
Display:
Here is an unordered list:

This list is
using a picture with CSS!
and now an ordered list:
This list is
using a picture
with CSS!
As you can see, it does not matter if the lists are <ul> or <ol> when using images. Nevertheless, it is a good coding practice to only use images for an unordered list. Ordered lists usually have an incremented(growing) value that appears next to each list item.

CSS List Position
With CSS it is possible to alter the indentation that takes place with your list items. See the example below for the trick of indenting your lists. You may only use keyterms when specifying the indentation.

CSS Code:
ul { list-style-position: inside; }
ol { list-style-position: outside; }
Display:
This list is
using inside
positioning with CSS!
and now an ordered list:
This list is
using outside
positioning with CSS!
Note: "outside" is actually the default setting for indentation.

List: All in One
It is possible to combine the above CSS techniques into one line of CSS. This is useful if you would like to have a list-style-type take the place of your list image, if the image is not able to be loaded.

CSS Code:
ul { list-style: upper-roman inside url("http://www.example.com/notHere.gif");}
Display:
This list's image did
NOT load correctly
But because we chose to include
A CSS list type, we avoided a bland list!
