Two horizontal lines and edit appearing at bottom of page – helpremoving

Hi,

I am using the Madhat theme and am having a little trouble at the moment.

I made a static front page and are using the featured content areas. I wanted however to have the page at the top so switched this round but now two horizontal lines are appearing at the bottom of the page between the end of the page and the ‘Recent Posts’ section. its also creating lots of excess space around the area which i would like to remove.

Any ideas on how i can remove these? Tried lots of things but cant see where they are coming from! Very new to code etc so a simple explanation would be great!

Thanks
