Odd/Even with a hidden class
If all you have is just one hidden class, then this would be trivial. But I suspect, there is no easy way out for more than 1 :/
HTML
<p></p>
<p></p>
<p></p>
<p class="hidden"></p>
<p></p>
<p></p>
<p></p>
CSS
p
{
height: 2em; border: 1px solid black;
}
p,
p.hidden:nth-child(even) + p:nth-of-type(odd) + p:nth-of-type(even) {
background: khaki;
}
p:nth-child(even),
p.hidden:nth-child(even) ~ p:nth-of-type(odd) {
background: indianred;
}
.hidden { display: none; }
