I found that quite a few ‘toolbar’ in web page is implemented with HTML tag UL and LI with style ‘float:left‘.
Fore example, with the help of FireBug it is easy to find this pattern in http://www.yahoo.com/.
Is there any reason for that? I don’t think that UL and LI are invented to create toolbar.
HTML was intended for semantics (what things mean), not presentation (what they look like). Since
<ul>represents an unordered list, and since a toolbar is conceptually just a list of items, this is sensible. Even StackOverflow does it!
