I use something like this, to avoid losing the "theme safe" (which I want to keep)
.startpage-navigation {
box-shadow: none !important;
}
.startpage .button-startpage {
background-color: rgba(0, 0, 0, 0.81);
}
button.button-startpage:hover {
border-color: var(--colorHighlight);
}
.button-startpage, button.active.button-startpage {
color: rgb(240, 248, 255);
}
button.button-startpage:after {
opacity: 0; /*probably this is not need*/
}
