How can I change the base breakpoint in Webflow so that the changes I make on one breakpoint do not affect another breakpoint, even if it is the base breakpoint?

By default, Webflow’s base breakpoint is the desktop (≥992px), and styles cascade down (to smaller breakpoints) and up (to larger ones if explicitly set). You cannot change the base breakpoint, but you can manage styling to minimize unwanted style inheritance.

1. Understand Webflow's Inheritance Model

• Webflow uses a mobile-first cascade, meaning:
• Desktop is the base breakpoint.
• Styles applied at the desktop cascade down to tablet and mobile.
• Styles applied in smaller breakpoints override the base but don’t affect it.
• You cannot promote a smaller breakpoint to be the new base.

2. Use Combo Classes and Style Isolation

• If you want a style to exist only on a certain breakpoint, use combo classes or unique class names.
• Example:
• Create a base class btn.
• On tablet, duplicate it as btn tablet and style this combo separately.
• This prevents changes on one breakpoint from cascading into others.

3. Use Custom CSS in Embed Elements for Isolation (Advanced)

• Although not recommended for beginners, you can isolate styles to specific breakpoints using custom CSS within an Embed component.
• Example: Use media queries like @media (max-width: 991px) for mobile/tablet.
• Keep in mind this bypasses Webflow’s built-in style system and requires manual management.

4. Plan Global vs. Breakpoint Styles Ahead

• Apply all global styles (like typography, spacing, positioning) at the desktop level.
• Make only necessary overrides when you switch to tablet/mobile.
• Use the Style overrides indicator (blue dot) in the Style Panel to track changes.

Summary

You cannot change the base breakpoint in Webflow—it is always desktop. To prevent styles from cascading unintentionally, use combo classes, apply overrides at specific breakpoints, and plan styles carefully across viewports.
