// Make viewport responsive
//
// @viewport is supposed to eventually replace <meta name="viewport">. It's manually prefixed for forward-compatibility.
//
// @viewport is also needed because IE 10+ doesn't honor <meta name="viewport"> in some cases.
// (See http://timkadlec.com/2012/10/ie10-snap-mode-and-responsive-design/)
//
// However, `device-width` is broken on IE 10 on Windows (Phone) 8,
// (see http://timkadlec.com/2013/01/windows-phone-8-and-device-width/
// and https://github.com/twbs/bootstrap/issues/10497)
// and the fix for that involves a snippet of JavaScript to sniff the user agent and apply some conditional CSS.
// See http://getbootstrap.com/getting-started/#support-ie10-width for the relevant hack.

// iOS "clickable elements" fix for role="button"
//
// Fixes "clickability" issue (and more generally, the firing of events such as focus as well)
// for traditionally non-focusable elements with role="button"
// see https://developer.mozilla.org/en-US/docs/Web/Events/click#Safari_Mobile
// Upstream patch for normalize.css submitted: https://github.com/necolas/normalize.css/pull/379 - remove this fix once that is merged
