The one you need is labeled "Render as:", third from below on the left in the large greenish block. It doesn't seem to do anything, though.
It will not do anything right away, but it should change when you submit the form. The one exception to this is when you are viewing a game where you are a player, because your preferences in the log will override what you entered in the form. I should fix it so that preferences in the log are more easily overridden. [BUG FIXED]
CSS rendering looks pretty ugly, though: all occupied squares get (1px wide black) borders, the rest of the board not.
That should not be happening, and I have not seen it. Where are you seeing this behavior?
