As suggested by FixSomeBugs here, I've edited common.css to widen the infoboxes. This makes it easier to fit long stat names without having to split it over multiple lines, and helps remove a lot of the empty space that was previously on the page. Animal infoboxes in particular significantly shorter and more compact now.
Imo it significantly improves readability, but because it affects the whole wiki I thought I'd get feedback on it.
I've also asked Jimyoda for feedback.
