What do you mean by inaccessible?
A bad CSS change couldn't for instance produce a blank page. It can eg.
make you lose the styles, but nothing too dramatic.
The easiest way to undo your change is to disable CSS in your browser
and revert that page. The wiki will look "funny" without CSS but is
completely usable.
