In-Depth Information

it's not yet known whether the CSS3 lists module will formally reinstate the keywords shown in
Figure
10-4
. However, it seems likely that you'll be able to define your own custom sequences in the future.
Note
Suppressing the Symbol
In addition to all these keywords is perhaps the most important one:
none
. h
is enables you to suppress the symbol
or number, which opens up the way to convert a list into a navigation bar.
Nested Lists
With unordered lists, browsers automatically change the symbol for each new level of nesting, as shown in
Figure
10-5
(see nested_ul.html).
Figure 10-5.
Browsers automatically change the symbol when unordered lists are nested
■
Note
The automatic sequence of symbols for unordered lists is fixed. it doesn't change if you reset the top-level
symbol.
Ordered lists keep track of the current number, starting again at 1 when moving to a deeper level, and
resuming the sequence when backing out of a nested list. Although this is convenient, the numbers are difcult
to follow because each level of nesting uses the default
decimal
value for
list-style-type
(see Figure
10-6
and
nested_ol.html).
