This is hugely important. I wish I could +1 you 10x. Understanding what you can do in CSS and what will require an image file or javascript to work is pretty important in designing an efficient site. I've seen designers with pretty looking ideas that are really difficult to implement. They say, "but you can do it right?" and it can be done, but they don't realize what they are asking for.
