I have been making a couple of css customizations to my moodle site (version 3.6.2) using boost theme, but I'm having one issue I hope you can help me with. I'd like to change the color of a selected menu/drop down menu item. I cannot seem to find the proper css rule to do this. So, for instance, I'd like to change the selected color in the settings menu within a course, but also in drop down menu's in various activities or in menus that are only available for teachers. I assume all these different situations rely on a single css rule, but I'm not sure if this assumption is correct.
Does anyone have any suggestions for me? Thank you very much in advance!
