Image banner blurry on mobile

Topic summary

A user reports that banner images appear blurry on mobile devices while displaying clearly on desktop across multiple pages of their Shopify store.

Affected Pages:

  • Homepage
  • Women’s collection
  • Men’s collection
  • Eid collection
  • New arrivals
  • About us page

Proposed Solution:
Another user suggests adding custom CSS code to adjust the banner minimum height on mobile devices (screens under 749px width). The code targets the .banner--large class and sets min-height: 97vh.

Implementation Steps:

  1. Navigate to Online Store → Theme → Edit Code
  2. Locate base.css, theme.css, style.css, main.css, or custom.css
  3. Add the provided CSS media query at the end of the file

Status: The issue remains unresolved as the user has requested additional help for all affected pages. It’s unclear whether the CSS solution addresses the underlying image quality/resolution problem or only adjusts banner sizing.
