Conceal text until hovered, similar to how several sub-reddits do it. Add this to your "Custom CSS":
/** Spoiler text */
.Post-body a[href='#spoiler'] {
color: #000 !important;
background-color: #000 !important;
&:hover, &:active {
color: #fff !important;
border-bottom: none;
}
}
Using it within a post, you write [text you want to concel](#spoiler) and it will show up as a black box until hovered.
