Would you have a simple submission like this?

a:active {
    filter: brightness(var(--active-brightness));
    text-decoration: none;
}

a:hover {
    filter: brightness(var(--hover-brightness));
    text-decoration: none;
}

a:focus {
    filter: brightness(var(--focus-brightness));
    text-decoration: none;
}

@bueltge Yea, that looks good. need to determine what those color/levels should be though.

Going to go with the text-decoration: none; for the time being. May revisit soon and see how color/transparency would work. Updated in https://github.com/tbolt/boltcss/tree/nov2022-updates
