No difference.
Just a reminder that this code you gave me worked. But since then there were patches that should have fixed it if I recall correctly.
body.woocommerce .wc-columns-container.wc-columns-3 .products {
grid-template-columns: repeat(3,minmax(0, 1fr));
}
Altough I used it as 2 columns under a breakpoint, and the !important was needed, else it didn’t work.
body.woocommerce .wc-columns-container.wc-columns-3 .products {
grid-template-columns: repeat(2,minmax(0, 1fr)) !important;
}
