Adjust width/height of code editor

Hello,

I’m really enjoying this plugin when I’m working with code.

One issue I’m having is, the editor goes over the right and bottom sides about 40px, so that I cannot resize it (resize handle is still visible). Also the scroll bar goes under the metabox on the side.

I’ve tried adjusting the CSS, but it’s not enough. Could you tell me how I can make the code editor a smaller so it fits in its space?

Thank you.
