Slideshow image banners failed to display on mobile, showing white boxes with text, while desktop worked normally. The store owner had tried prior suggestions without success and shared a preview link.
Proposed fix: add a mobile-specific CSS rule in the theme’s main CSS file (base.css/style.css/theme.css). Code: a media query for screens up to 749px setting “.slideshow__media.banner__media.media:first-child { display: block; }”. This targets the mobile breakpoint so the slideshow media shows instead of being hidden.
Outcome: Applying the CSS resolved the issue for the original poster, confirmed with a result screenshot.
Follow-up: Another user reported a similar problem (video background shows on mobile, but two images below do not). They asked if the same code works universally. No confirmation was provided. The helper noted a page error when attempting to access that user’s site, so their case remains unresolved.
Status: Original issue resolved; secondary case open pending site access and verification. Code snippet is central to the fix.
