Shrink white space below slider

Hi Sakin, I see you offer fantastic support and hope you are able to help me :) We are using the free Catch Everest theme and its working well for us - but my Director would like me to shrink the white space around the text underneath the post slider - I found a support ticket you replied to where you can reduce this to zero but that is too much for our purposes but altering it just puts it back to the standard spacing. www.a1ba.co.uk Thanks in advance for your help!
