How to put the thumbnail images on the left side of the main product image of the dawn theme?

Topic summary

A user seeks to reposition product thumbnail images from the bottom to the left side of the main product image in Shopify’s Dawn theme.

Initial Solution Attempts:

  • First CSS code targeting section-main-product.css with flex-direction reversal failed to work
  • Second, more comprehensive CSS code for base.css successfully repositioned thumbnails to the left

Key Resolution:
The solution worked after enabling “thumbnail carousel” in the product page settings within the theme customizer—a critical step initially overlooked.

Follow-up Issues:

  • One user successfully implemented the code but wants to customize thumbnail size, shape (rectangle vs square), and spacing between thumbnails
  • Another user reports the code created a long vertical list instead of maintaining the carousel functionality
  • Some users cannot locate the “thumbnail carousel” option in Dawn theme settings

Additional Resources:

  • A YouTube tutorial link was shared for displaying thumbnails vertically
  • Alternative CSS code using rotation transforms was provided for vertical thumbnail display

The discussion remains active with ongoing customization requests and implementation challenges.

Hi @Dawood_Mirza_1 ,

your code worked great for me, thank you! Can you tell me how I can adjust the size and form of the thumbnails? I would like them to be

  • at least twice as big as they are displayed now
  • a rectangle instead of a square
  • and I would like to add space between the thumbnails

Thank you!
