Making text unselectable [duplicate]

Answer 1

It varies per browser. These CSS properties will target WebKit and Gecko-based browsers, as well as any future browsers that support user-select:

user-select: none;
-webkit-user-select: none;
-moz-user-select: none;

Answer 2

In IE you can make text immediately within an element unselectable (i.e. doesn't apply to text in its children) by using the unselectable="on" attribute.

Note that if applying from javascript you MUST use el.setAttribute("unselectable","on"). Just trying el.unselectable="on" will not work. (Tested in IE9).
