[Theme: Picolight] Quick and Easy, have a look…

Hi guys,
I posted earlier on having issues with the Yoko theme, I’ve abandoned the pursuit and found myself much happier with the picoclean theme. It’s all fantastic, except for one issue – I can’t seem to figure out how to get the white padding/margin? around the header and running all the way to the bottom footer to go away! It’s surrounding all the content, and I just want the width of the content to be in line with the banner/header at the top – so the black on the banner blends with the black in the background, if that makes sense.

My website: clickie

This is usually pretty simply, changing the width of the content to a different size so that it all shrinks, but this theme has been written oddly (for me) and I can’t figure out what is going on.

The code for the CSS Stylesheet is as follows:

Which is where it should be, right? Any suggestions before I head off to bed?
