4.1. Changing the Format of a List

Problem

You want to change the default list style, for example to change the bullet or numbering as in Figure 4-2.

The list markers changed to lowercase Roman numerals

Figure 4-2. The list markers changed to lowercase Roman numerals

Solution

Use the list-style-type property to change the bullet or type of counter:

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

Discussion

The CSS 2.1 specification offers several styles for numbering a list, as shown in Table 4-1. Browsers typically vary the bullet style from one level of nesting to the next. To stop lists from presenting this traditional system of setting the list marker, change the value of list-style-type for each child list.
