I've been using the IE Developer Toolbar to debug styling problems in custom Community Server skins. It's been very useful except that in some cases, I couldn't easily figure out why a property had a particular value. For example, exactly which style is setting the font-weight to bold?
Yesterday, that problem was solved for me. The IE team uploaded beta 3 of the developer toolbar. It includes a very handy feature call Style Tracer. If you select an element, the current style is displayed in the bottom panel. If you then right click on one of the style properties and choose Trace Style from the popup menu, a window appears, downloads the style sheet, and sets focus to the controlling style.
