If your background images set to “Fixed” aren’t appearing fixed on mobile devices (e.g., iPhone 8+, LG G7 ThinQ, iPad Air 2), it's because mobile browsers do not fully support CSS background-attachment: fixed.
1. Mobile Browser Limitations
- Most mobile browsers (including Safari on iOS and Chrome on Android) disable
background-attachment: fixed to improve performance and reduce resource usage. - This is a known limitation, not a Webflow bug.
- Even though you can apply
background-attachment: fixed in Webflow, it will downgrade to scroll or behave unexpectedly on mobile devices.
2. Platform-Specific Behavior
- iOS devices (including iPhone and iPad models) specifically ignore background fixed to preserve battery life and maintain smoother scrolling.
- Android browsers generally follow a similar approach, although there may be slight variations between brands and OS versions.
3. Workarounds in Webflow
To mimic fixed background behavior on mobile, try one of the following:
- Use a Div Block with a background image inside a fixed-position element and layer it under your content.
- Set the Div Block to
position: fixed, top: 0, left: 0, with width: 100% and height: 100%. - Place your background image in that div and set it to
cover and center. - Then, place your page content in a higher z-index container.
- Use interactions (scroll-based animations) to create a parallax-like effect instead of relying on fixed backgrounds.
- Use Lottie animations or video backgrounds if technically feasible and performance allows.
4. Avoid Styling for Fixed on Mobile
- Consider setting different styles for mobile breakpoints:
- Go to Tablet, Mobile Landscape, and Mobile Portrait view in Webflow Designer.
- Set the background attachment to “Scroll” instead of “Fixed” using conditional styling.
- This creates a fallback for mobile users while maintaining fixed visuals on desktop.
Summary
Mobile browsers block background-attachment: fixed by design, which is why fixed backgrounds fail on devices like iPhone 8+, LG G7 ThinQ, and iPad Air 2. Use custom fixed-position elements or interactions as workarounds and avoid relying on fixed backgrounds for mobile layouts.
