I have the following CSS that hides the mouse cursor for anything on the web page. It works perfectly in Firefox, but in IE and Chrome, it doesn't work.
html {
cursor: none;
}
In Chrome, I always see the mouse pointer. In IE, however, I see whatever cursor was last 'active' when it entered the screen. Presumably it's keeping the last selection instead of removing it.
This property cursor:none;
isn't part of the standard
See here w3c cursor CSS properties.
You might want to look into hiding it with Javascript or JQuery.
Also, look at blank cursor files here.
And one last link to an ajax solution.
Chrome has had this issue since it was built, there have been reports sent to the people at Chromium, and I assume they are working on it.
Also, don't trust that anything would work in IE. Ever. :P
