How to remove white space between page content and footer?

Hi guys. I have a site here: https://prettystars.co.uk/

I’ve tried lots of CSS tweaks to get rid of the big white space between the bottom of the content in the pages and the footer. But nothing works…

In this screenshot – https://prettystars.co.uk/wp-content/uploads/2015/11/white-space.jpg – it’s the bit between the words Top quality, best prices, best service and free, fast delivery! and the images in the footer.

Any help would be really appreciated!
