This used to work perfectly on my site but has recently stopped working on Chrome:
<a href="javascript:document.getElementById('cite1').style.display='block';">
Cite
</a>
<div style="display:none; font-size:10pt; margin-top:11px; margin-bottom:7px;" id="cite1">
Information goes here
</div>
It used to correctly make the text appear, but now it changes the entire page to a white screen with the word "block" on it.
Any ideas why?
