Values

scroll → const BackgroundAttachment

The background is fixed relative to the element itself and does not scroll with its contents. (It is effectively attached to the element's border.)

const BackgroundAttachment('scroll')

fixed → const BackgroundAttachment

The background is fixed relative to the viewport. Even if an element has a scrolling mechanism, the background doesn't move with the element. (This is not compatible with background-clip: text.)

const BackgroundAttachment('fixed')

local → const BackgroundAttachment

The background is fixed relative to the element's contents. If the element has a scrolling mechanism, the background scrolls with the element's contents, and the background painting area and background positioning area are relative to the scrollable area of the element rather than to the border framing them.
