Images in the feed start as grayscale and when hovered over, transition to full color.
CSS
#sbi_images .sbi_item {
filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); /* Firefox 10+, Firefox on Android */
filter: gray; /* IE6-9 */
-webkit-filter: grayscale(100%);
-webkit-transition: all .6s ease;
-webkit-backface-visibility: hidden;
}
#sb_instagram .sbi_item:hover {
filter: none;
filter: none;
-webkit-filter: grayscale(0%);
}
To hide the hover area (opaque overlay that appears when hovering) add this CSS
#sb_instagram .sbi_photo_wrap:hover .sbi_link {
opacity: 0 !important;
}
