Dawn Theme: make the image banner adapt to image size on mobil view

Topic summary

A user seeks help making the Dawn theme’s image banner display full-screen on mobile devices instead of being cropped, despite having implemented a feature to show different mobile images.

Proposed Solutions:

  • CSS height adjustment: Modify section-image-banner.css by locating .banner--large:not(.banner--mobile-bottom):not(.banner--adapt) .banner__content and changing min-height from 34rem to 50rem or 125vw to fit mobile needs.

  • Custom CSS injection: Add specific CSS code to theme.liquid before the </body> tag to control mobile image display behavior.

Current Status:

The original poster confirmed one solution worked for them. However, another user reported the suggested fixes didn’t resolve similar spacing issues on their mobile homepage banner, indicating the problem may require site-specific adjustments.

Hello everyone, I’ve added a feature to my image banner section that enables me to display a different image on mobile views, but the issue is that the image is cropped when viewed on mobile devices. Could someone kindly offer assistance so that the image can be displayed in full screen on mobile views?

Hi,
To make the mobile image full height, please go to Assets/section-image-banner.css file and find (ctrl+F) .banner–large:not(.banner–mobile-bottom):not(.banner–adapt) .banner__content.
Under the .banner–large:not(.banner–mobile-bottom):not(.banner–adapt) .banner__content tag, please change the min-height value to fit your neeeds.

From
min-height: 34rem;

To
min-height: 50rem;

Or
min-height: 125vw;

Hope it helps.
Thanks.
