Teacher Style front Page Tiles

[Jeremy Hopkins]

This is related to #378 and the styling of the front page tiles where the "teacher" text color does not seem to be applied (see image below).

The "teachers" class seems to be missing, we can add this with something like:

.coursebox.hover .teachers {
color: #ffffff !important;
}
