Link with class in CSS

Now let the links themselves have a class:

html<a href="#" class="eee">link</a>
<a href="#" class="eee">link</a>
<a href="#" class="eee">link</a>

Let's set styles for links that have this class:

cssa:link.eee, a:visited.eee {
  color: red;
}
a:hover.eee {
  text-decoration: none;
}

It doesn't matter in what order you write the reference class and state pseudo-classes. You can rearrange them and nothing will change:

cssa.eee:link, a.eee:visited {
  color: red;
}
a.eee:hover {
  text-decoration: none;
}
