Making fee consistent with rest of page/site

Hello,
I am using this plugin to display a twitter feed as a widget in the left sidebar. My user has the following requests:

1. Use the same font – typeface and size – as the content on the rest of the page/site.

2. Align the widget with the page, i.e., don’t indent it from the left of the page.

I’d appreciate any help with making this happen.

Thank you,
Andrew
