To make pages and wiki look nicer as a whole. You'll run into it eventually; when everything else is finished, you'll want to spice it up even more. That's when CSS comes to stage.

Also, it is hard to answer what particularly you can do with CSS. Just open some wikis as an example. You'll notice that certain elements do not look or function as they should be.
