/* Document
1. Change from `box-sizing: content-box` so that `width` is not affected by `padding` or `border`.
2. Change the default font family in all browsers.
3. Correct the line height in all browsers.
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.
