Resize logo img

Hello everyone,

I know it’s such a noob question but how do I resize the logo img? I checked style css and couldn’t find the code to change height I think width is set at 100% so that’s no problem but take a gander at http://travelamazed.com and you will see what I mean.

I’m using WordPress 3.9.1 running ElegantFusion theme.

Any help would be very much appreciated.

Chris
