I’ve been trying to get my main content to be in the centre of the page for ages! I’ve tried a few things - one which I thought seemed very logical, to set the left and right margins to 10% and the width to 80%.

This was not yielding the results.But with the help of these guys:

I have discovered the beauty of the auto margin. For some reason setting the left and right margins to auto and giving it an actual width.

To give you a feel for how this is coming along - I have uploaded a test:
