1. There is no option shown to controle grid size in your linked guide.
https://xtemos.com/docs-topic/image-size-and-content-alignment-in-a-product-grid/
The elements are added by germanized to grid. And germanized told us if your theme is compatible with germanized you will be able to share custom css to controle that elements.
And yes, i know we can controle that elements by custom css. But the problem is: if we do that, some more elements in cart also change the sizes. So please tell me how to change the text-size and text-color only for that elements from my screenshot.
2. And your link also not show how to set all grids to same height like other themes which looks much better by having same grid high. Also grids with more elements have same height. Your grid jumping in sizes and thats not looking good. I have checked your linked guide and that also no help in this point.
