post widgets problem

Hello guys, I'm beginner in internet marketing and also I'm learning how to create websites right now, so I've encountered a little problem on my site, I've got wordpress engine and I wrap post titles in H1 tag, in recent posts widget links show up enormously big, can someone tell me how to resize it and make it more good-looking??

Hopefully you have figured it out by now but if not... secret is in the CSS. The H1 might have an ID= associated with it, so search for that ID in the style sheet and there you go.
Example: TwentyEleven HTML= <H1 id="site-title"> CSS = #site-title - By default the font-size:30px so just adjust until your happy.
