Resizing image to fit image banner at Dawn

Technical Q&A

Topic summary

Issue: Image in the Dawn theme’s Image banner is being cropped; resizing the source image has no effect, and the Adapt image option makes it appear too large. Goal: fit to a medium banner height without cropping.

Actions and outcomes:

  • A custom edit in theme.liquid (main layout file) above the closing body tag resolved sizing for the poster by adjusting a max-width parameter. The exact code wasn’t provided in the thread, but the key tweak was changing max-width to control banner size.
  • Another participant fixed width behavior by switching from a percentage (e.g., 40%) to a fixed pixel value (e.g., 1100px) for max-width.

Related issue and fix:

  • Banner looked darker than surrounding areas. Setting the Image banner opacity slider in theme settings to zero removed the dark overlay.

Open questions:

  • How to apply the custom code to all Image banners on a page (not just one).
  • How to change the banner container height to prevent bottom cropping.

Status: Partially resolved via custom CSS and opacity adjustment; some implementation details remain unanswered.

I actually ended up using a similar code that I already inserted to my theme.liquid file:

So if anyone has the same issue just paste this in theme.liquid above the written at the bottom, and use the 1’st max-width parameter to change the size of the banner.
