// 4. Prevent adjustments of font size after orientation changes in IE on Windows Phone and in iOS.
// 5. Setting @viewport causes scrollbars to overlap content in IE11 and Edge, so
//    we force a non-overlapping, non-auto-hiding scrollbar to counteract.
// 6. Change the default tap highlight to be completely transparent in iOS.
