How To Change Slideshow Image Size For Mobile Only

Topic summary

Using the Shopify Dawn theme, the slideshow image looks right on desktop but appears too small on mobile; the requester wants a larger mobile slideshow (site: retrokingstonmerch.ca).

Suggested fix: add a CSS media query to the theme’s base.css (in Assets) that only applies on mobile (max-width: 749px) and increases the slideshow image height for the .media > img element (example value 176px, adjustable), enforced with !important. A screenshot was provided to illustrate the change. Briefly: CSS (style rules) and media queries (conditions like screen width) let you apply mobile-only styling.

Alternate view: another participant says the current mobile UI/UX looks good and no changes are needed.

Outcome: no confirmation from the requester; the thread remains open. Actionable next step is to try the mobile-only CSS and tweak the pixel height to the desired size.

I am using Dawn theme and the slideshow image is the perfect size on desktop, but too small on the mobile version.

Hi @SteveT2112 !

This is PageFly - Advanced Page Builder. I would love to give you some recommendation;

Please paste this code at the bottom of base.css under assets in theme code files;

@media screen and (max-width: 749px) {

.media > img {

height: 176px !important;

}

Bro You can change px as you want.
