To add the outline to the images so that they display like those of Instagram Stories Highlights, I first set the list in style tiles, circle shape… Then I Used the code below, but only this list must be in tile styles on the screen, otherwise the circle will appear below too and it won’t be very pretty.
<pre><span><style>
.tile-inner {
padding: 3px 1px;
}
.tile-image-area {
border-radius: 50%;
box-shadow: inset 0px 0px 0px 15px white;
}
.tile-image-area:before {
content: '';
position: absolute;
top: 0; right: 0; bottom: 0; left: 0;
z-index: -1;
margin: -3px;
border-radius: inherit;
background: radial-gradient(circle at 30% 107%, #fc4e03 40%, #fc4e03 65%, #fc4e03 45%,#fc4e03 60%,#ffb508 90%);
}
