HTML and CSS Reference
The styles in numbered_headings_style.html have been amended like this:
content: counter(chapter) '.' counter(section, lower-roman ) ' ';
content: counter(chapter) '.' counter(section, lower-roman ) '.' counter(subsection,
lower-alpha ) ' ';
This changes the style of the numbers to look like Figure 15-8 .
Figure 15-8. You can style the numbers in the same way as ordered lists
Changing the Size and Direction of the Increment
By default, counter-increment increases the sequence number by 1. To change the size of the increment, add an
integer after the counter name separated by a space. You can also use a negative number to count in reverse.
