I like perfect
but before I change the other styles, let me give you (and anyone else who's interested) the details in case we can get this even better.
Width is designated in pixels, and these settings govern not only the code block but also the php and quote blocks. Here are the defaults and what I changed them to:
default Experimental
container 510 680
header 502 672
body 500 670
So...should I do some tweaking, or go ahead and update the other styles to the new numbers?
