Is this still the thing to do?
I am working with the Supply theme for now, & it doesn't respond the best on mobile. Should I edit the code with this graphs thingy?
In order to display everything correctly on mobile, you should open product.liquid template and add "grid _item" class to these blocks:
- <div itemprop="description" class="grid__item product-single description rte">
- <div product-handle="loyalty-couple-bracelet" class="grid_item ryviu-reviews-list">
- <section class="grid_item related-products">
The screenshot gwa-mobile-friendly.png displays how it will be displayed after the changes.
