Change accordion tab background color when hover over

I would like the background color of the tab to change when I hover over an inactive accordion tab. I tried quite a few different things without luck.

I managed to change the active background color of the active tab with the following code:

div.fl-accordion-item.fl-accordion-item-active .fl-accordion-button {
background-color: #b3030e;

Does anyone here have a good suggestion :slight_smile:
