[Tutorial] How to change theme width?

[eNvy]

Tip: MyBB has a 20px of padding in each side (left and right), so, if you want to have a 1024px width, you need to:

1024 - 40 (20px padding left, and 20px padding right) = 984px

That's the width for 1024px (With 20px padding).

P.D.: I know, it's a silly thing xD.
