Twenty Ten Spacing

Hello,

I’m using a Twenty Ten theme and I have Jetpack installed. I also have the Custom CSS stylesheet installed to tweak bits and pieces.

I want to know how to remove the extra space at the bottom of my content page – above the widgets. There’s a huge, empty space.

Have a look at my website to see what I mean: http://www.impactcopywriting.co.uk

I guess I just need the code to type into CSS?
