Align products in mobile

Good evening

I need your help regarding the display of 2 products per category for mobile.

I have version 4.7 which I don’t want to change because it works well, the customers are satisfied but I can’t align the 2 products on the page.

I managed to make 2 products on the page from 1 product with this css

@media screen and (max-width: 480px) {
.ty-column4 {
width: 50%;

But the problem is that some products are not lined up well.

The theme is VIVA SHOP (I tried to talk to them but they said they didn’t have time)

I also attached a picture…

Thank you!
