My image banner is not full screen with space by the side

Topic summary

Issue: A homepage banner in the Dawn theme shows space at the sides and doesn’t appear full-width.

Key updates:

  • After the store link was shared, the cause was identified as whitespace within the uploaded image itself (not a theme/layout issue). An annotated screenshot highlighted the extra margins. The recommended fix is to crop the image to remove side whitespace and re-upload.
  • The original poster acknowledged this guidance with thanks.

Alternative suggestion:

  • A later tip proposed adding custom CSS in base.css to force banner height: .banner { height: 288vh !important; } via Online Store → Theme → Edit code. This suggestion was not confirmed by the original poster.

Status:

  • The practical resolution appears to be cropping the image. No further issues or confirmations were reported after the CSS suggestion.

Notes:

  • Images (screenshots with highlighted areas) were central to diagnosing the issue.

Hey @torisamorgan ,

Can you share the link to your store please? Thanks!

Hey @torisamorgan ,

It’s actually your image that has whitespace on the side. You should put crop it out (The blue highlight)

ok, thank you very much

Hi @torisamorgan

You can try this code by following these steps:

Step 1: Go to Online Store->Theme->Edit code.

Step 2: Search file base.css

Step 3: Paste the below code at bottom of the file → Save

.banner {

height: 288vh !important;

}

Hope that my solution works for you.
