Styling Ordered Lists

Moving on to lists, you'll begin by styling an ordered list. You'll modify the marker type and then replace the marker altogether with an image. I began with some text and background styles along with an unstyled ordered list, resulting in Figure 10-9.

Figure 10-9. A styled page with an ordered list.

If you want to use an alternate marker, you can do so using the list-style-type property with a corresponding value. There are numerous values (most supporting numerals in other languages), but the ones you'll likely want to swap in an ordered list are decimal-leading-zero (which starts the numbering at zero) and lower-roman or upper-roman (which use lower or upper Roman numerals, respectively). Simply add the value you want to the existing style sheet:

ol {list-style-type: lower-roman;}

This results in the numerals displaying in lowercase Roman (see Figure 10-10).

If you'd like to replace the numerals with an image, create images for each number you require and apply classes to each list item to get the results (see Example 10-6).

You can see not only the relevant CSS here, but also see the rules I created for the rest of the page styles (see Figure 10-11).
