Hi there,

How can I reduce the spacing between these 2 rows of thumbnails from my Instagram feed?

@niteshifte You can try this code snippet:

.sqs-gallery-block-grid.sqs-gallery-aspect-ratio-standard-vertical .slide .margin-wrapper a.image-slide-anchor {
	padding-bottom: 125% !important;
}

THANK YOU!!!
