Thank you, I will do that!
Thanks, yes I have – but I dont quite understand how to use them – especially in my case
YEAH, I found the solution for having a fullscreen image with ratio, simply put this into the custom field:
background-position: center top;
background-attachment: fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
It seems like dills solved his problem.
Could somebody point out the solution?
