Internet Explorer Compatibility
Earlier versions of Internet Explorer (IE8 and earlier) did not support HTML5 elements.
The share of Internet Explorer 8 is only 0.77% according to caniuse.com for May 2016. Despite this, some websites are still being developed taking into account the specifics of this browser. HTML5 Shiv allows early versions of Internet Explorer to recognize HTML5 tags.
