Hiding the mouse cursor when idle using JavaScript

Question

Is it possible to use JavaScript to set the cursor attribute to the property none if the mouse is inactive for a certain amount of time (say, five seco

Answer 1

In CSS 2 none is not a valid value for the cursor property. It is valid in CSS 3, however.

Otherwise you might be able to use a custom cursor loaded from a URI that is simply transparent.

I would consider this to be highly distracting for the user, though, so I wouldn't advise you to actually do that.
