Reduce hight homepage headline

Hi! I was wondering if it's possible to reduce the height of the homepage headline? Id like to make it slightly thinner using html if that's possible. Any help would be greatly appreciated! If I have the code I can adjust the height on my own based on what looks good. Thanks so much in advance! If you're confused what I'm talking about, it's the blue banner that says "Check out the latest posts from Adventures Around Asia" http://www.adventuresaroundasia.com Thanks!
