Change styling for a mod

Hi,
I have a question about the Sid nav section mod (possibly it applies to others). How can I change the text and highlight colours of the left hand menu items?

Hi there! If you’re referring to this mod (not sure if you are)

Then you could do it with CSS rules that override bootstrap. For example, for the left hand menu item:

.nav .nav-link.active {
  color: white;
  background: red;
}
