It looks like the custom CSS you added to adjust forum row text is causing an issue on mobile. Find the
.node-extra-row class and confine it to a
min-width: 600px media query so it will no longer apply past screens smaller than 600px.
Code:
@media all and (min-width: 600px) {
.node-extra-row {
overflow: hidden;
white-space: nowrap;
word-wrap: normal;
text-overflow: ellipsis;
color: #acb1b5;
}
}
The actual cause of the issue is the
white-space: nowrap; line, but it seems worth nulling the entire selector on mobile.
