the browser responsible for compliant rendering of exceptional cases,
either.
7.3.1. Changing the Style and Sequence of Individual List
Items
Just as you can change the bullet or numbering style for all of the items
in an unordered or ordered list, you can change the style for individu-
al items within those lists. With ordered lists, you also can change the
value of the item number. As you'll see, the combinations of changing
style and numbering can lead to a variety of useful list structures, par-
ticularly when included with nested lists. Do note, however, that the
standards have deprecated these attributes in deference to their CSS
counterparts.
7.3.1.1. The type attribute

have their
type
set to
circle, square
, or
disc
, and items in an ordered
list may have their
type
set to any of the values shown previously in
Be careful. With earlier browsers, such as Netscape Navigator and Inter-
net Explorer versions 4 and earlier, a change in the bullet or numbering
type in one list item similarly affected subsequent items in the list. Not
so for HTML 4-compliant browsers, including Netscape version 6, Inter-
net Explorer versions 5 and later, Firefox, and Opera! The
type
attrib-

<li>
tag. Subse-
quent items revert to the default type; each must contain the specified
type.
The type attribute changes the display style of the individual list item's
leading number, and only that item, but not the value of the number,
which persistently increments by one.
