Hello,
I have added below code to child theme style.css of the test site.
@media only screen and (max-width: 1200px){
.template-container .product-category.columns-5:nth-child(5n+1) {
clear: none;
}
}
@media only screen and (max-width: 767px){
.template-container .product-category.category-grid.columns-5 {
width: 50%;
}
.template-container .product-category.category-grid.columns-5:nth-child(2n+1) {
clear: both;
}
}
@media only screen and (max-width:480px){
.category-grid .categories-mask {
zoom: 0.8;
}
}
Check now.
Regards
