Disabling text selection and copying on a webpage with CSS

To prevent dragging to select text with the mouse and disable selecting or copying page content, simply add the following CSS to the body's style.

/* css style: */ html,body{ -moz-user-select: none; -khtml-user-select: none; user-select: none; }

Notes: unselectable is for IE; onselectstart is for Chrome and Safari; -moz-user-select is specific to Firefox.
