What could be causing the background images to not appear as fixed when viewed on mobile devices like iPhone 8+, LG G7 ThinQ, and iPad Air 2 in Webflow?
TL;DR
- Most mobile browsers do not support
background-attachment: fixed, causing fixed backgrounds to appear scrollable on devices like iPhones and Androids. - Use Webflow scroll interactions or fixed-position divs with layered content as alternatives for consistent cross-device visual effects.
Background images set to "fixed" may not appear stationary on some mobile devices due to platform and browser limitations. This behavior is not caused by Webflow directly but by how mobile operating systems handle background-attachment.
1. Understand the Limitation of background-attachment: fixed on Mobile
- Most mobile browsers (iOS Safari, Android Chrome, etc.) do not support
background-attachment: fixeddue to performance and rendering constraints. - On devices such as iPhone 8+, LG G7 ThinQ, and iPad Air 2, the browser disables the fixed positioning to maintain smooth scrolling and better performance.
2. Confirm Your Webflow Background Settings
- Check your element settings: Ensure your background style has Attachment set to Fixed in the Webflow Designer.
- Make sure the background image is applied to a block element with sufficient height, or it may not render as expected even on desktop.
3. Use Alternative Methods for Fixed Background Effects
- For mobile responsiveness, consider using a parallax scroll effect via interactions instead of relying on
background-attachment: fixed. - Apply Webflow Interactions 2.0 (scroll-based animations) to mimic a fixed or parallax effect that works cross-device.
- Alternatively, use a full-screen image inside a fixed-position
div, and layer your content on top.
4. Avoid Relying on Fixed Backgrounds for Mobile UX
- Due to the broad lack of support, it’s best to avoid fixed backgrounds for mobile designs or use alternative styling/fallbacks.
- Consider setting a different background style on mobile breakpoints in Webflow. Example: change background attachment to Scroll or use mobile-specific images.
Summary
Background-attachment: fixed is not supported on most mobile browsers, so background images may not appear fixed on devices like iPhone 8+ or iPad Air 2. Use scroll-based Webflow interactions or layout workarounds to achieve a similar visual effect that works across all devices.
