Your CSS injection is messed up, and it is not how we suggested it..... Please read carefully.
This is not the RIGHT way at all..
@media (min-width: 992px) {
.DiscussionPage-nav, .DiscussionPage-nav>ul {
position: sticky;
top: 80px;
}
.Post::before, .Post::after {content:none;}
section {
width: 950px;
}
.App {overflow-x: visible;}
}
This is:
.Post::before, .Post::after {content:none;}
@media (min-width: 992px) {
.DiscussionPage-nav, .DiscussionPage-nav>ul {
position: sticky;
top: 80px;
}
.App {overflow-x: visible;}
}
