The responsive-font-size property

This text automatically rescales thanks to PostCSS RFS. It uses the RFS algorithm to automatically calculate the appropriate font size based on the dimensions of the monitor or device.

There is also a mixin availible which uses the same technique: RFS mixin. You can play with the configuration on this codepen demo.

Currenty there is an open feature-request to put RFS in Bootstrap: Responsive font sizes. The result of RFS in Bootstrap is shown on the bootstrap RFS demo site
