I'd like to add this one, which can allow you to give your profile a background image even with body CSS being broken:
h1, div { background: url("https://3dspaint.com/images/upload_gallery/9548.jpg" center center / 100% fixed !important;}

I left some out so if body CSS works again there is no need for your solution, but currently (at the time of this writing) it is working but doesn't on my profile
