How Much Is Too Much?

HelloIm wondering what is the best practice for using qualified selector statements.Take these examples:

#mv_bottomcontainer.oncelogged #left div.mv_smallGrayBoxCont div.mv_smallGrayBoxMiddle #cib_bar div.left{color:white;font-size:12px; etc....}

#mv_bottomcontainer.oncelogged #left #cib_bar div.left{color:white;font-size:12px; etc....}

#cib_bar div.left{color:white;font-size:12px; etc....}

All three examples should result in the same elements getting styled. But which is more performant? Which would allow for faster page rendering times?Thanksps. I know we are probably talking milliseconds of difference here, but as a whole-er stylesheet it would make seconds of difference!

It's pointless to have an ID selector under a descendent selector, since you're completely sure that you're only going to have one element with that ID in the whole document. That's to begin with.The difference between one selector and another isn't in milliseconds, but microseconds, so it doesn't make a difference even if you have five stylesheets of 30kb each. The total time will be practically the same no matter how ridiculously long you make the selectors.
