I would do it with simples method available - setting background-image that is aligned top and horizontally centered:
- Code: Select all
body {
background: transparent url(../img/to/bg/file.jpg) 50% 0 no-repeat;
background-attachment:fixed;
}
Before that, I wuld disable all other changes made to template background, and also disable default background.
This way code used in override.css will works ok.
