RFS is a unit resizing engine that automatically rescales CSS values like font-size, margin, padding, and border-radius based on viewport dimensions. It is available as mixins/plugins for Sass, Less, Stylus, and PostCSS.

Use cases

  • make font sizes responsive across viewports
  • fluidly rescale padding and margins in css
  • prevent text from being chopped off on small screens
  • keep typography proportional across breakpoints
  • replace manual media queries for font resizing
  • rescale css values with sass or postcss

When to choose

  • you use Sass, Less, Stylus, or PostCSS and want fluid, viewport-based value scaling
  • you want readable text on small screens without hand-written media queries
  • you want consistent proportional scaling of spacing and typography

When to avoid

  • your project uses plain CSS without a preprocessor or PostCSS
  • you need fixed, non-fluid sizing
  • you rely on a CSS framework that already handles fluid typography
