[Plugin: Random Text] Adding some style….?

I’m setting up the following blog:
http://bsgsociallearning.com/

At the top of the sidebar I’ve installed the randomtext plugin, which works perfectly.

The only problem I am having is I can’t get a proper border/underline like the other widgets in the sidebar.

I was also wondering if there is a way to edit the appearance of how the text shows up… is there a way to add any style to the plugin through css?

Thank you.
