A user wants their collection banner image to display as a square with responsive sizing, matching the behavior of product images on their store.
Proposed Solutions:
Two respondents provided nearly identical CSS-based fixes:
Add custom CSS code to the base.css file (found in Online store > Themes > Edit code)
Target the .collection-hero__image-container class
Set max-width: 550px !important to control the banner dimensions
Status:
The discussion remains open with no confirmation from the original poster about whether either solution resolved the issue. Both solutions appear technically similar, suggesting consensus on the approach.

I would like for my Collection Banner image to have the exact same size as my Product images, aka that the image stays a square and that the size of the square adapts to the size of the screen.
