How can I resolve the issue of my website not functioning properly on mobile sizes in Webflow?

If your Webflow website looks or behaves incorrectly on mobile devices, it’s likely due to layout or styling issues specific to smaller breakpoints.

1. Check and Use Mobile Breakpoints

• In the Webflow Designer, click the device icons at the top to preview your site on different breakpoints (Tablet, Mobile Landscape, Mobile Portrait).
• Webflow allows you to custom-style each breakpoint, but changes cascade downward—meaning changes on desktop affect mobile unless overridden.

2. Look for Overflow or Fixed Widths

• Inspect elements with fixed widths (like 800px) that don’t scale on smaller screens. Use percentage widths (e.g. 100%) or max-width settings instead.
• Check for any elements causing horizontal scrolling by having large width/margin/padding values on mobile.
• Use the Navigator panel to inspect nested elements and ensure no parent containers force unwanted sizes.

3. Adjust Positioning and Flex Settings

• Elements with absolute or fixed positioning may shift or overlap other content on smaller screens.
• Review Flexbox and Grid settings to ensure elements wrap properly or stack vertically on mobile.
• Use tools like Display: Block vs. Flex vs. Grid carefully per breakpoint.

4. Use Responsive Typography and Spacing

• Update font sizes to use viewport-based units (vw/vh) or rem/em, which scale better across devices.
• Check the spacing (margin, padding) on mobile: large desktop padding can look broken on small screens.

5. Hide or Adjust Content for Mobile

• Use Webflow’s visibility settings to hide or modify components on specific breakpoints if they don’t work well on mobile.
• Duplicate and customize elements separately for mobile using Show/Hide on different breakpoints, if necessary.

6. Verify Media and Interactions

• Ensure images and videos use max-width: 100% and appropriate settings like object-fit.
• Interactions or animations triggered by hover or keyboard inputs may not translate well to mobile—test them and adjust triggers if needed.

7. Publish and Test on Real Devices

• After making changes, Publish your site and open it on a real phone or use browser dev tools to emulate various devices.
• Consider using Webflow’s Preview mode + device toggles, Google Chrome’s Device Emulator, or physical device testing.

Summary

To fix mobile issues in Webflow, inspect and adjust styles on mobile breakpoints, ensure layouts are responsive (no fixed widths or overflow), and adapt interactions or content visibility for mobile devices. Always publish and test responsively before going live.
