I've been taking a really close look at the examples over at CSSZenGarden because one of the things that makes me crazy, as a designer, is when someone resizes the text, in <div> and <span> layouts, you often have overlaps ... and it looks like crap, frankly. I've found several designs that look good, regardless of the browser, resolution OR text size, and just found This One - utililizing the expanding menu option - that renders somewhat differently in different browsers, but retains the style and readability. I like it.
