-webkit-tap-highlight-color: rgba(0,0,0,0); on a div?
Are you writing for iPhone/Smartphone websites? If so, then yes. But you'll probably only see the results on your phone/simulator. I think that this element can only be used on links or javascript elements. The div would have to be affected by some kind of scripting, or be a link.

This should work:
-webkit-tap-highlight-color:transparent
I applied this to all (*) of my html objects for my iphone web-app.
Simply add this to your css code:
*{
/* Prevent any object from being highlighted upon touch event*/
-webkit-tap-highlight-color: rgba(0,0,0,0); }
I used jQuery mobile to add and handle touchstart and touchend events to my buttons, which handles the background-image of my buttons (actually these are div
s), so it looks like they are pressed down on touchstart.
