Desktop browsers render background-attachment: fixed beautifully — the classic parallax effect where the content scrolls over a still background. Mobile browsers don’t: iOS ignores the fixed attachment and paints the image against the element itself, so a tall section with background-size: cover shows up as a hugely stretched, blurry texture. Android is inconsistent at best.
OXP Mobile Fixed Background repairs this automatically. On touch devices it detects every element with a fixed background image, removes the broken background, and re-creates it on an invisible layer with the exact dimensions of the screen, fixed to the viewport and clipped to the element’s box. The result is what background-attachment: fixed was always supposed to look like — on any theme, with no configuration.
