Add the HTML5Shiv:

<![endif]-->HTML5 introduced a method to control over the viewport, through the <meta> tag.
The viewport is the user's visible area of a web page. It varies with the device, and will be smaller on a mobile phone than on a computer screen.
You should include the following viewport element in all your web pages:
<meta name="viewport" content="width=device-width, initial-scale=1.0">The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device).
The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.
