I was looking at how to change the cursor over an HTML5 canvas when dragging the mouse... Came across this: Change cursor over HTML5 Canvas when dragging the mouse
seemed logical that an :active pseudo-selector would do the trick...
When I used it on my page, however, the cursor set by the rule in the :active pseudo-selector was ignored, instead showing the text selection cursor.
In firefox, this behavior is not present - it obeys the cursor property I set.
Here's an example to demonstrate the behavior.
Any idea how to fix this in chrome?
Add the following for Chrome to turn off text selection while dragging and dropping.
document.onselectstart = function(){ return false; }
