Hide text node in element, but not children

I'm having a little trouble with CSS and can't seem to find a solution. I have this HTML

<div id="closelink">
  <a href="">Close</a>
  Click to close
</div>

Now I want to hide the text «Click to close» only, without hiding neither the div, nor the link within it.

Can this be done?

Solution 1:

The visibility attribute can be overriden on children elements, so you are able to do this:

#closelink {
  visibility: collapse;
}

#closelink a {
  visibility: visible;
}

<div id="closelink">
  <a href="">Close</a> Click to close
</div>

.closelink {
  font-size: 0px;
}

.close-link a {
  font-size: 12px;
}
