I have a header set to 1/3 of the of the site. I have a background image set to
'... cover centre center no repeat fixed'
and have a parallax effect applied to it by skrollr. (This set up works best so far)
It works close to how I want it but it crops the image when the window is resized. The image has important information in the middle which I want visible no matter the size of the screen/header. I've seen it done where the image ratio says the same when div size changes and the majority of the image and its placement stays the same.
What is he best way to accomplish this?
