HOw do I change the font size of my widget title?
 

Please take a look, the "Recent Tweets" title in the left sidebar is too big.

Also why does the "Recent Tweets" widget not have a border? The other widgets have borders.

this was asked a couple days ago, do a search of the forum with 'widget font' and you'll find the answer.
