How can I add a custom background image on multicolumn (using Dawn theme)

Topic summary

Goal: add a custom background image to the multicolumn section in Shopify’s Dawn theme, matching a full-width banner look (reference: honeywellaircomfort.com).

Proposed approaches:

  • Edit multicolumn.liquid to add an image setting (picker) and render it in the section’s HTML.
  • Add CSS in base.css targeting the specific multicolumn section class (e.g., .section-template–…-padding) with background-image, cover, center, no-repeat, and upload the image to Settings > Files to use its URL.

Latest update: The provided CSS solution did not work for the requester. They shared a new preview link and screenshots, clarifying they need the background’s width, height, and placement to mirror the reference site.

Context notes:

  • Preview links expired and were refreshed; screenshots are central to understanding the desired layout and dimensions.

Status: Unresolved. Next steps likely require correcting the CSS selector (ensuring it matches the section’s actual class/ID) or implementing the image as a configurable setting in multicolumn.liquid to reliably control full-width background behavior.

Hi @erika_brandlab1 ,

To add background image we need to customize the multicolumn.liquid file. You should create a image section in the liquid code and add it in the html.

  1. You find the file base.css and add the following code at the end of the file:
.section-template--17118277304601__e1225a6b-f8d2-4be2-b2c0-9e9ee69013fe-padding  {
  background-image: url("your-image-url");
  background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
  background-clip: content-box;
}

For “your-image-url”, you can add the following:

From Shopify admin → Settings → Files, you upload the file and then use that image link.

I hope that this can help you solve the issue.
