Conditionally Load Styles

This an experiment to load untranspiled styles in modern browsers, but transpiled ones in old ones.

We can use -ms-high-contrast to target browsers running on Windows. Theoretically, this would also target Edge. Luckily, -ms-high-contrast: none is not supported in Edge anymore.

The other way round, any well-supported Media Queries Level 4 value will never be supported in IE11.

This means we can use (pointer: fine), (pointer: coarse), (pointer: none) to target new browsers.


The following box will be blue and have a border-radius of 0 if your browser supports -ms-high-contrast: none.

If your browser supports the pointer media query, it will be violet and have a rounded corner.
