Is there a css pseudo selector for overflow?

问题

I'm trying to alter the style of something based on wether or not its parent div is being overflown.

.pDiv { display: block; width: 300px; height: 100px; border: 1px solid rgb(0,0,0); }
.cDiv { display: block; padding 4px; border-bottom: 1px solid rgb(0,0,0);
.pDiv:overflow .cDiv { border-bottom: none; }

<div class="pDiv"><div class="cDiv">child 1</div><div class="cDiv">child 2</div><div class="cDiv">child 3</div><div class="cDiv">child 4</div><div class="cDiv">child 5</div></div>

is it possible to do something like this? I would use the last-child pseudo-selector, but the number of children can vary, so I want it to remove the border-bottom of the last-child ONLY IF the parent div is being overflown. I want a pure CSS solution too please, no JS!

回答1:

CSS cannot select based on used or computed styles of any kind, so you're out of luck.
