block-content-gallery.html not working as it should

Hello,

Apologies for the Issues and Thanks for reporting this. The following code was missing:

@media (min-width: 576px) {
	.card-columns {
		-webkit-column-count: 3;
		-moz-column-count: 3;
		column-count: 3;
		-webkit-column-gap: 1.25rem;
		-moz-column-gap: 1.25rem;
		column-gap: 1.25rem;
		orphans: 1;
		widows: 1;
	}
	.card-columns.grid-2 {
		-webkit-column-count: 2;
		-moz-column-count: 2;
		column-count: 2;
	}
	.card-columns > * {
		display: inline-block;
		width: 100%;
	}
}

This will definitely work fine. We will fix this in the next update. Hope this Helps!
