I would like to mark the links the already read with a hook. Unread links should not display the hook. The rule is the visited link, and can differ only in color.
Would it be the fine to put the hook of the unread link transparent?
Or is there a better solution?
a.readed {color: rgba(0, 255, 0, 1)}
a.readed:visited {color: rgba(0, 255, 0, 0)}
<a href=""> goto</a><a href="" class="readed"> ✓</a>
