IE8 Specific allowances

IE8 does not support media queries or REM units so natively a Foundation 5 based site will not render well on IE8. While IE8 usage remains a significant albeit diminishing user base, some JavaScript polyfill solution is used to mitigate these shortcomings.

In the <head> element:

<!--[if lt IE 9]>

<link rel="stylesheet" href="css/ie8.css" />
<script src="//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.6.2/html5shiv.js"></script>
<script src="//s3.amazonaws.com/nwapi/nwmatcher/nwmatcher-1.2.5-min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/respond.js/1.1.0/respond.min.js"></script>

<![endif] -->

Before the closing <body> element:

<!--[if lt IE 9]>

<script src="js/rem.min.js"></script>

<![endif]––>
