Hello,

Thank you very much for choosing our theme and for contacting us.

Please add this code to the Theme Settings > Custom CSS > Global:

.wd-hover-standard .wd-add-btn a{
    display:block;
}
.wd-action-btn.wd-style-text>a {
    font-size: 20px;
}
body .product-grid-item {
    margin-bottom:50px!important;
}

As for the gap between items: I have sent 50 px, however you can change this value as per your needs.

If you have any questions please feel free to contact us.

Best Regards
