Regarding the thumbnail position in main product

Topic summary

Goal: Move product image thumbnails from below the main image to a left-side vertical layout across all product pages (Vivid theme).

What happened:

  • Store URL was shared. A helper suggested adding custom CSS in theme.liquid under the tag, with screenshots attached. Initial code produced no visible change.
  • The helper suspected the code wasn’t saved or applied to the correct theme. The change appeared to work on only one product, not sitewide.
  • A revised snippet was suggested, but the merchant modified selectors with incorrect classes, so the CSS didn’t apply properly. The helper pointed out the class issues.

New issues:

  • A “too long” thumbnail div appeared; the merchant says this was fixed.
  • Slider navigation buttons are not working. The helper noted the buttons hadn’t worked from the start and were hidden via CSS (display: none).

Current status:

  • Partial success on layout; not consistently applied across all products. Slider buttons remain non-functional. No confirmed resolution.

Notes and next steps:

  • Correct theme-specific selectors for Vivid and apply CSS globally.
  • Review JavaScript for the slider component and reinstate/hook up navigation buttons (remove display:none if needed).
  • Screenshots and code snippets are central to diagnosing this.
