How can I fix the issue where the 320px screen size overrides higher screen sizes and affects specific elements such as pictures on my Webflow project? This is causing frustration and delays in my work. Thank you for any assistance in resolving this problem.

You're facing an issue where styles set at the 320px breakpoint are overriding larger breakpoints and affecting elements like images. This is likely due to styles being applied on smaller breakpoints that are not correctly overridden upwards, or custom CSS affecting global behavior.

1. Understand Webflow’s Breakpoint Inheritance

• Webflow uses a cascading system, meaning styles from larger breakpoints cascade downward (desktop → tablet → mobile).
• However, styles applied on smaller breakpoints do NOT inherit upwards to larger ones. If you style something specifically at 320px, it won't affect 768px unless you reused or duplicated those elements and styles improperly.

2. Check for Styles Applied Specifically at 320px

• With the mobile portrait breakpoint (320px) active, click on the affected image or element.
• Look at the Style selector (Class) and sidebar.
• Remove or reset any unintended overrides—especially layout (width, display, margin) or image sizes—unless they’re meant only for mobile.

3. Use Style Overrides Properly

• Start styling from the Default (Desktop) breakpoint.
• Apply general styles on Desktop, then refine those styles downward (Tablet → Phone).
• Avoid applying universal styles at 320px, such as setting a class-wide style, unless it's responsive.

4. Check Global or Combo Classes

• If your image uses a combo class (like .image.large-mobile) edited only at 320px, that style may bleed into higher breakpoints if the combo class is reused.
• Keep styles clearly scoped to each breakpoint or duplicate base classes as needed.

5. Verify Custom Code or Styles

• Go to Project Settings > Custom Code, or check Page Settings.
• Look for any custom CSS or <style> tags that may use !important or mobile-focused media queries incorrectly.

6. Clear Unused or Conflicting Styles

• Use the clean-up feature: In the Webflow Designer, click the Style Manager tab (the paintbrush icon) and remove unused classes.
• This helps avoid inheriting outdated or unnecessary styles.

Summary

The issue is caused by styles set at the 320px breakpoint overriding or incorrectly influencing larger viewports, which shouldn't happen if Webflow's cascading model is followed correctly. Review and restructure styles from the Desktop down, avoid styling only at 320px, and clean up conflicting or global styles tied to mobile breakpoints.
