-webkit-palm-mouse-target
From WebOS101
Set a div to "-webkit-palm-mouse-target: ignore;" to have it ignore user events and pass the events to elements below. This is useful if you want an icon to hover over a scroller, for instance, and you don't want the icon to interfere with the scroller functionality.
Note that this property only works when applied to DIV elements. It doesn't work on image elements. Furthermore, it seems that the div elements cannot be set to "display: inline;".
Also note that this property seems to be ignored by the text inside a div. In testing, a click on the inner text would trigger a parent div's click, regardless of whether or not there was a legitimate element physically underneath the click. Also, when doing this, if the parent div had a mouse event that triggered, the event's element() would be the div with -webkit-palm-mouse-target:ignore set, not the parent element.
