Hello,
Thank you very much for choosing our theme and for contacting us.
As for the product categories on mobile, this is caused by different title lengths. Please add this code to the Theme Settings > Custom CSS > Tablet/Mobile/Landscape:
.cat-design-default .wd-entities-title {
min-height:45px;
}
body .cat-design-default .hover-mask{
min-height:90px;
}
As for the checkout, the translation is longer than the original which is why it is broken.
Please try this code to the Theme Settings > Custom CSS > Global:
@media (max-width: 400px){
table.woocommerce-checkout-review-order-table th,
table.woocommerce-checkout-review-order-table{
display:inline-block;
}
table.woocommerce-checkout-review-order-table tfoot tr,
table.woocommerce-checkout-review-order-table tfoot th{
display:block}
}
Best Regards
