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?
- Mobile browsers disable background-attachment: fixed, so fixed background images won’t work reliably on mobile.
- Use scroll-based animations or substitute background images with positioned image elements to mimic the effect, and apply fixed backgrounds only on desktop breakpoints.
Background images with a "fixed" setting in Webflow may not appear correctly on mobile devices due to mobile browser limitations.
1. Understand Mobile Browser Limitations
- Mobile Safari and other mobile browsers do not consistently support the
background-attachment: fixed;property. - To improve performance, mobile devices often disable background-attachment: fixed entirely.
- Your fixed background settings may work in the Webflow Designer preview or desktop modes but fail on actual devices.
2. Check Your Section and Style Settings
- Go to Webflow Designer and select the section with the background image.
- In the Background settings, check that Attachment is set to Fixed.
- Even with this setting applied, it won’t override the mobile browser’s native behavior.
3. Use Alternative Techniques
To achieve a similar fixed effect, consider these alternatives:
Create a parallax scroll effect using interactions:
Use Webflow Interactions to animate background position or image movement based on scroll progress.
This creates the illusion of a fixed background without depending on background-attachment.
Use a Div with an Image inside instead of a background image:
Place an Image element inside a section.
Use absolute positioning to keep it stable while content scrolls over it.
Limit fixed background usage to desktop devices only:
In the Style panel, set background attachment to "Fixed" on desktop breakpoints.
Then switch to smaller breakpoints (Tablet, Mobile Landscape, Mobile Portrait) and set background attachment to Scroll or use an alternative style.
4. Test on Real Devices
- Simulators may not reflect real behavior—test on actual devices when verifying the fixed background effect.
- Tools like BrowserStack or direct device testing are more reliable than the Webflow preview.
Summary
Mobile browsers do not support background-attachment: fixed, which prevents fixed background images from appearing correctly on devices like iPhones, iPads, or Android phones. To solve this, use animation-based parallax effects or alternative layout techniques for mobile views.
