I am trying to make my background image (the header media) positioned at the top of the screen, rather than centered. In other words, I don't want the top to be clipped out: only the bottom. This could be as simple as "background-position: center top", but I spent an hour trying to find where to implement this code, with no success...
The website is www.latelierdegaia.ch
First of all its not a background .. its an image which is positioned as u can see in screen shot. http://jmp.sh/MYGDtcX
make this height auto and it will fix the issue hopefully.

height:auto;
