How to change collection page banner size

Topic summary

Goal: adjust the collection page banner size and add a sidebar to match a provided reference design on a Shopify store.

Current status: one member shared a CSS approach; another offered general design help; a subsequent participant reports they cannot change the banner height and requests further assistance. No confirmed resolution yet.

Proposed solution: add CSS in base.css using media queries to tweak desktop layouts:

  • For wide screens (min-width: 1630px) and mid-range screens (1025–1629px), the code targets “#HeaderCollectionSection-template–22595065446718__banner .collection-header.container-1170”.
  • It adjusts padding-left and max-width to reposition/enlarge the header content. A result screenshot shows improved alignment/spacing.

Limitations/open questions:

  • The shared CSS modifies padding-left and max-width, which affects layout/alignment but not explicit banner height. The height issue remains unresolved.
  • Sidebar implementation (as in the reference image) was not provided; only an offer to help privately.

Media: multiple screenshots are central—one reference layout, one current site, and a result showing the CSS effect.

Outcome: discussion is ongoing; specific instructions to change banner height and add a sidebar are still needed.
