To prevent text selection of any element use:
in Firefox, Opera and Webkit based browsers (Chrome, Safari, etc) this can be achieved by setting a CSS property.
-webkit-user-select:none; -moz-user-select:none; -o-user-select: none; user-select: none;
user-select is part of the CSS3 standard.
For IE < 9 we have two options:
Using javascript:
onselectstart="return false;"
and using the HTML attribute
unselectable="on"
