Reformation theme - collection product image size

Topic summary

A user is attempting to display 8-10 product columns on desktop for their collection page in the Reformation theme, but adjusting the column slider in theme settings produces no effect.

Proposed Solution:
Another user provided CSS modification instructions:

  • Navigate to Online Store > Themes > Customize > Edit code
  • Locate app.css around line 942 (or 924)
  • Replace existing media query code to adjust product width percentages

Current Status:
The original poster reports confusion about locating the exact code:

  • Line 942 doesn’t contain the specified entry; line 924 does
  • After adding the suggested code at line 924, no visual changes occurred
  • Questioning whether certain code sections should be deleted

The issue remains unresolved, with the CSS solution not producing the desired multi-column layout. The discussion appears ongoing with no confirmed working fix yet.

Hi @AmberWilkinson ,
To reduce product image size.
Do followiing steps:

1.Go to your Shopify admin panel.

2.Navigate to Online Store > Themes.

3.Find your theme and click on Customize.

4.Click Actions > Edit code.

5.In the left sidebar, under the Layout directory, select app.css line number:942
Search this code:

@media only screen and (min-width: 769px) {
.medium-up--one-fifth {
width: 10% !important;
}
}

Replace with this code:

@media print, screen and (min-width: 66.75em) {
.large-4 {
flex: 0 0 33.33333%;
max-width: 33.33333%;
}
}

then save your changes
Result:

Where do I find this under the Layout directory, select app.css line number:942

It was line 924 - i added the code but nothing changed

942 doesnt have that entry - 924 does.

@media (min-width: 1024px) { .collection-item { width: calc(100% / 8); /* Adjust this number for 8-10 columns */ } }

Do I delete /* Adjust this number for 8-10 columns */

None of these solutions have been concise.
