You should make the clickable target area larger, i.e. to select the "<a>"-tag I have to click on the little "a"; it would be much easier to just click on the gray box surrounding the "a".

Still, I'm not really happy with menus in webpages. It takes several clicks to get the needed information. Maybe you should consider making the information text beyond each tag visible all the time; I'm talking about the "This element defines an anchor..." kind of text. It's always easier just to scroll than having to click.
