// Hide all posters except the topic author
.topic-list .posters {
width: 75px;
text-align: center;
// Only show first poster
a:not(:first-of-type) {
display: none;
}
// Get rid of offset and decoration
a:first-child .avatar.latest:not(.single) {
position: static;
box-shadow: none;
border: 0;
}
// Adjustment for center alignment
& > a {
float: none;
margin-right: 0;
}
}
// Make sure the correct user is showing at smaller width
@media screen and (max-width: 850px) {
.topic-list td.posters {
// Ensure first poster is showing
a:not(.latest) {
display: block;
}
// Hide everything else
a:not(:first-of-type) {
display: none;
}
}
}
