I'm trying to put the image on the bottom behind the image on the top to make a border around the image. I realize that the image isn't formatted correctly just yet and that's the next part. I'm using wordpress. I set the z-index for each to 1 (border) and -1 (image) and I tried messing with the margin, padding, position but they didn't do anything.
Here's the code on JSFiddle: https://jsfiddle.net/5L8mnfdc/
#pl-9 .panel-grid-cell .so-panel {
z-index: 1;
}
.sow-slider-base ul.sow-slider-images li.sow-slider-image .sow-slider-image-container {
z-index: -1 !important;
}
