Fixed background image

I have set the background image of a box to be fixed so that a transparent box will scroll over it revealing the fixed image as you scroll down the page. This works great on a computer and even in Safari’s Responsive Design Mode works great on the smallest screen, however on an actual phone (iPhone 12 I’m testing on) the transparent box doesn’t scroll over the background image, it’s like the transparent box just is filled with a section of the image. Happy to upload the document if needed, but here is a link:

and here are the setting I have on the box with the background image:

Unfortunately, it seems that Fixed background attachment has limited support in mobile browsers. It seems to have been disabled in iOS for performance reasons.

Ah… bummer, thanks for the info!
