Note: I don't know CSS from a hole in the ground and this is my first time trying to edit a style sheet.
Here's my website: http://naturalbeginningsutah.org/
On my 13" Mabook the image fits the screen. On my 15" or 17" with a different resolution, it doesn't.
If I recall correctly, the place to enter the code would be under
Appearance> Theme settings> CSS, right? I've copied/pasted about a dozen codes to try and fix it and nothing works.
I also saw this thread: http://wordpress.org/support/topic/set-margins-for-white-space-1?replies=6, but I'm not sure if that's my problem since on the 17" there is white space at the bottom as well.
There are other kinks for me to try and work out but this is my biggest issue at the moment.
Thank for you any help!
