Change 'gap' width

Hi Guys,

Very basic question here – I am using a gap between two sections and am able to change the height of it, but I don’t seem to be able to adjust the width…

I have a sample page here:

All I want is to make the red bar at the bottom the same width as the entire section above (its just an empty section coloured red, with a single 20px gap in)… I suspect I am missing incredibly simple. But please let me know, its been bugging me for hours.

Ignore this everyone, I was being silly! I had set the section background colour different to the column!
