PostCSS Safe Area

PostCSS plugin that adds browser fallbacks for safe-area env variables.

Old iOS and Android browsers don't support environment variables that are required for CSS safe areas. This plugin adds all neccessary fallbacks, and supports calc() as well as shorthand properties for multiple margin or padding values.

.foo {
  padding-top: env(safe-area-inset-top);
  margin: 5em 5em calc(5em + env(safe-area-inset-bottom)) 5em;
}

.foo {
  padding-top: 0;
  padding-top: constant(safe-area-inset-top);
  padding-top: env(safe-area-inset-top);
  margin: 5em 5em calc(5em + 0px) 5em;
  margin: 5em 5em calc(5em + constant(safe-area-inset-bottom)) 5em;
  margin: 5em 5em calc(5em + env(safe-area-inset-bottom)) 5em;
}

Install this dependency using

npm install postcss-safe-area --save-dev

Now you can use the plugin using

postcss([require('postcss-safe-area')])

See PostCSS docs for examples for your environment.
