Here is a quick CSS image fix for the uddeIM navigation bar:
#uddeim-navbar2 ul li img,
#uddeim-overview img {
display: initial;
vertical-align: initial;
}
#uddeim-navbar2 ul li img {
margin-bottom: -3px !important;
}
There is much more left to fix! If I get some free time, I try to create a more complete CSS override for "Bootstrap". The issue with uddeIM is, that you can't create real overrides for the output. Markup and default CSS have a very specific structure... A real pain to target and re-style everything.
