Removing Padding with CSS

I’m trying to remove the padding between the header and the main photo on the homepage to my site http://www.wearepangaea.com.

I am using theme junkie custom Css plugin.

The problem I’m having is finding the location on my site. I’ll open up the inspect element and I can find the green highlighted area that I want to remove but I’m not sure what code to type into my custom Css

Any info would be greatly appreciated!
