// 1. Change from `box-sizing: content-box` so that `width` is not affected by `padding` or `border`.
// 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.
// 7. rem单位由16px转化到100px,对于开发H5页面时就只需要，移动两位小数点即可
