How can I enhance mobile banner image quality using Dawn theme?

Topic summary

A Shopify store owner using the Dawn theme is experiencing blurry banner images on mobile devices, despite having already improved desktop image quality through custom code.

Initial Solutions Attempted:

  • Uploading higher resolution images (suggested but didn’t resolve the issue)
  • Modifying the image-banner.liquid file by changing the assign widths values to include larger dimensions like ‘3750, 3000, 2400, 2000, 1500, 1100, 750’
  • Multiple iterations of width adjustments were tested but continued to show blurry results

Resolution:
The original poster eventually solved the quality issue by re-saving the image in Photoshop, which significantly improved clarity.

Secondary Issue - Clickable Link:
After the image quality fix, the banner lost its clickable functionality. This was resolved by adding CSS code with opacity: 0 !important; to a specific section.

White Gap Problem:
Replacing the code created an unwanted white space above the banner. The fix involved adding height: 0px !important; to the CSS media query targeting .banner__content.banner__content--middle-center.page-width.

Status: The original issue is resolved. A separate user (Dh7oom) later reported similar banner quality problems but encountered password access issues when seeking help.
