The reason that margins collapse between child and parent is the same as the reason they collapse between siblings. Consider the following XHTML2-like markup:

Note: If the tags above got treated as markup, the example is:

I need some help with the Asktheseguys wordpress theme..
I can't figure out how to get the header and ad bar at the top to go all the way across the screen.. Or better yet, how I can place an ad box in the empty space at the top right.
I can usually figure this stuff out easily, but can't find anything in the CSS that will make it work..
Anyone have any ideas?
