How to increase size of product detail image gallery thumbnails?

Recommended Posts

Hi - I am looking for a way to increase the overall size of the thumbnails that appear beneath the main product image. They are really small and would love to make them more visible. If anyone has an idea for how to be able to increase the height of them so that 3-4 images take up more space beneath the main product pic I would appreciate it! Thank you!

I'm also trying to achieve this.

Is there any code for making product thumbnails bigger?



Add to Home > Design > Custom CSS

/* thumbnail image bigger */
.ProductItem-gallery-thumbnails-item {
    width: 100px;
    height: 100px !important;
.ProductItem-gallery-thumbnails-item img {
    width: 100% !important;
    height: auto !important;
    left: 0 !important;
