(Dawn Theme) Banner's Not Showing On Mobile View

Store Design

Topic summary

Mobile banner images on a Shopify Dawn theme are not appearing in the mobile view. An earlier solution from another thread did not work for this store.

Recent attempts:

  • A mobile-only CSS rule setting a fixed height (33vw) for a specific banner ID was added to base.css. This restored the first banner but not the second.
  • A follow-up CSS aimed to apply a height to all banners with the “banner–adapt” class, but the banners stopped showing again.

Technical details:

  • CSS changes used a media query (max-width: 750px) and viewport-width units (vw) for height.
  • The user shared the Image Banner Liquid section code. It conditionally adds “banner–adapt” and uses a ::before element with padding-bottom based on the image’s aspect_ratio to control height. This code is central to the issue.

Status and open questions:

  • No final resolution yet; the second banner still fails, and generalized CSS caused regression.
  • Likely related to missing/conditional banner height and Liquid logic on mobile. Next steps may require verifying class selectors, consistent height for all banners, and reviewing the Image Banner Liquid for inconsistencies.

Hi,

Your banner’s height was gone. Try to paste this code to the base.css under the Asset folder.

@media only screen and (max-width: 750px) {
#Banner-template--15333557567721__1635804658ed6a1565 {
height: 33vw !important;
}
}

@sherichdigital

Please add the following CSS code to your assets/base.css bottom of the file.

@media only screen and (max-width: 750px) {
#Banner-template--15333557567721__1635804658ed6a1565 {
height: 33vw !important;
}
}

Thanks!

it worked to get the first banner showing, but not the second.

@sherichdigital

Seems like all your banners did not have a height. Replace the code with this.

  1. Open the code editor.

  2. Under the Asset folder, open the base.css and add the code at the very bottom

@media only screen and (max-width: 750px) {
.banner banner--adapt {
height: 33vw !important;
}
}

now it’s not showing again

Maybe it’s the image banner liquid coding causing the issue?

Here is the code:

{%- if section.settings.adapt_height_first_image and section.settings.image != blank -%}
{%- style -%}
#Banner-{{ section.id }}::before, #Banner-{{ section.id }} .banner__media::before {
padding-bottom: {{ 1 | divided_by: section.settings.image.aspect_ratio | times: 100 }}%;

display: block;
}
