I'm currently still running version 7.9.3373.0 and have finally found some time to upgrade to the latest version (8.1 SP5)
I have to redo all of the styling, which is for the most part going well, but I cannot seem to find a way to change the styling for the Background cells on the hour.
I currently have something like this to have slightly darker lines on the hour, is this possible in the new version?
border-bottom: solid 1px #333;
border-bottom: solid 1px #999;
