Use a control character in HTML rather than a GIF for a bullet. Even though a bullet GIF might be quite small, browsers render control characters more quickly than they can download a graphic, and it would reduce the number of connections the user's computer has to make to the server.
Control characters (such as ) may render somewhat differently on different browsers, particularly between Macs and PCs, but they'll almost always show up as some sort of bullet. The advantage control characters have over the more conventional <LI> element is that they can be individually colored, as our example shows.
I am Arthur, King of the Britons<BR>
King of the who?<BR>
I am Arthur, King of the Britons
King of the who?
