that's not a Wix code question but a maybe someone came acros the solution I was looking for since long...
Currently, when you load the Wix-Home page wix.com (without beeing logged in) there is an image taking exact 100% of the screens hight. When you resize the browser the image is also rezized. But it seems not to be a page background as when you scroll down the page, this background-style image is scrolled too.
Did anyone got this working with wix? Apparently it should be possible as they use it on their own page, but doesn't need to be available for public or beta useres.
Thanks in advance!
