Thank you Usman, now it works 🙂

Hi Usman, thank you, sadly it does not work when I add it to the additional css in the theme.

Moreover, the plugin CSS does not have such a class, only those, none of which have the background-color attribute:

.qe-faqs-filters-container {
list-style: none;
padding: 0;
margin-bottom: 1em;
}

.qe-faqs-filters-container li {
display: inline;
padding: 0;
margin: 0;
}

.qe-faqs-filters-container li a {
display: inline-block;
border-bottom: 1px solid;
padding: 5px 10px;
margin: 0 10px 0 0;
}

.qe-faqs-filters-container li a:hover {
border-bottom: 2px solid;
}

.qe-faqs-filters-container li.active a {
border-bottom: 2px solid;
font-weight: bold;
}
