Hi there,
He actually used this plugin: https://wordpress.org/plugins/gp-social-share-svg/
Then he added a Hook Element to the after_entry_header
hook with this content:
<div class="floating-container">
[gp-social]
</div>
Make sure to execute shortcodes and set the Display Rules to single posts.
Then he added this CSS:
@media (min-width: 840px) {
.floating-container {
display: block;
position: sticky !important;
position: -webkit-sticky !important;
top: 80px;
height: 0;
}
#gp-social-share {
top: 1em;
flex-direction: column;
left: -50px !important;
}
}
