Login Background dynamically change size - Possible?

[nerder 0]

So, I found an image I'd like to use which is 1920x1080, and have applied it to be absolute and to fill the browser page, however is it possible to make it if the view is lower than 1920x1080 to have the size remain the same, yet if the view is 1920x1080 or greater to have it scale?

Pending on which selector your using, you can tweak it with:

background: url('IMAGE') center center no-repeat;
background-size: cover;

Example:

#loginPage {
  position:             absolute;
  color:                #000000;
  left:                 0;
  right:                0;
  margin:               0 auto;
  content:              " ";
  background:           url('//192.168.1.3/assets/img/emby/background.jpg') center center no-repeat;
  background-size:      cover;
}

Sorry, this took so long, I just noticed your post... hope it's still helpful.
