Hi,

I'm trying to make integrated instagram posts to 3 columns on Mobile view.

I've tried few codings that I've found but it's not working.

If anyone can help that will be great.

Thanks.

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
div#block-151f173c71b781f81b12 .slide {
    width: 33.33% !important;
}
}
