Where you have… You are trying to define CSS as if it were HTML, with  where you should have   instead.

To make it "slightly bigger" you can add a height property:

…and then maybe center it vertically and horizontally:

This is all just CSS defined as an "inline style" in HTML. The only difference is it's being placed in a table made with wikitext/wikimarkup, so you don't see it in the HTML tags. …this is supposed to make things easier 😆

As far as how to learn things… I dunno really… I've just been editing on Wikia for about 6 months. Trolling the forums here helps me learn new things, either when questions are asked and answered, or even when I go looking for answers to someone else's question and figure it out right then and there.
