What is HTML5Shiv?
HTML5Shiv is a JavaScript workaround, created by Sjoerd Visscher, to enable styling of HTML5 elements in versions of Internet Explorer prior to version 9, which do not allow unknown elements to be styled without JavaScript.
HTML5 Shiv only for Internet Explorer browsers less-than version 9.
