How can I make my Webflow site responsive and suitable for mobile and tablet devices without affecting the desktop version? I've tried making changes, but they seem to impact both the desktop and mobile versions. Can someone explain how to modify the mobile site specifically?

You're encountering an issue common in Webflow’s responsive design workflow—changes made at larger breakpoints (like desktop) cascade down to smaller ones (tablet, mobile). To tailor your site for mobile without affecting the desktop layout, follow these steps using Webflow's built-in responsive tools.

1. Understand Webflow’s Cascading Breakpoint System

• Webflow uses a mobile-first, cascading style system, which means styles applied at a desktop level flow down to smaller breakpoints unless overridden.
• Changes on desktop affect tablet and mobile, but changes on mobile only affect mobile (and not tablet or desktop).

2. Use the Breakpoint Selector

• At the top of the Designer, click the device icons to switch between breakpoints: Desktop, Tablet, Mobile Landscape, and Mobile Portrait.
• Always make changes within the breakpoint you want to affect only.

3. Modify Elements at the Target Breakpoint

• Once on the mobile (or tablet) view, you can:
• Change font sizes, spacing, layout (e.g., flex direction), margins, and other visual styles.
• Use Display: None to hide elements only on mobile.
• These changes will not apply to desktop unless you made them first on a wider breakpoint.

4. Avoid Deleting Elements for Responsiveness

• Don’t delete elements from mobile views to hide them—use visibility settings (Display: None) instead within the Styles panel.
• Deleting an element at any breakpoint removes it from all views.

5. Utilize Style Classes Wisely

• If an element needs an entirely different mobile style, you can:
• Duplicate the element, assign a new class name, and set one to show only on mobile and the other only on desktop.
• Use Combo Classes to tweak styles without creating fully separate classes.

6. Test Responsiveness in Preview Mode

• Click the eye icon (Preview mode) and resize the browser, or use Webflow’s device buttons to test mobile responsiveness.
• Ensure content flows correctly, nothing overlaps, and users don’t need to scroll horizontally.

7. Use the Navigator for Layout Control

• Use the Navigator panel to rearrange or wrap elements if mobile alignment breaks.
• Consider adding flex or grid containers that change direction or arrangement responsively.

Summary

To modify your Webflow site for mobile without affecting desktop, always switch to the specific mobile breakpoint, apply style overrides there, and avoid editing desktop styles when adjusting mobile layouts. Use visibility settings, combo classes, and the responsive preview to maintain control across all devices.
