CSS Modules: Local by Default

Transformation examples:

Selectors (mode local, by default)::

.foo { ... } /* => */ :local(.foo) { ... }

.foo .bar { ... } /* => */ :local(.foo) :local(.bar) { ... }

/* Shorthand global selector */

:global .foo .bar { ... } /* => */ .foo .bar { ... }

.foo :global .bar { ... } /* => */ :local(.foo) .bar { ... }

/* Targeted global selector */

:global(.foo) .bar { ... } /* => */ .foo :local(.bar) { ... }

.foo:global(.bar) { ... } /* => */ :local(.foo).bar { ... }

.foo :global(.bar) .baz { ... } /* => */ :local(.foo) .bar :local(.baz) { ... }

.foo:global(.bar) .baz { ... } /* => */ :local(.foo).bar :local(.baz) { ... }

Declarations (mode local, by default):

.foo {
  animation-name: fadeInOut, global(moveLeft300px), local(bounce);
}

.bar {
  animation: rotate 1s, global(spin) 3s, local(fly) 6s;
}

/* => */ 

:local(.foo) {
  animation-name: :local(fadeInOut), moveLeft300px, :local(bounce);
}

:local(.bar) {
  animation: :local(rotate) 1s, spin 3s, :local(fly) 6s;
}

Pure Mode

In pure mode, all selectors must contain at least one local class or id selector

To ignore this rule for a specific selector, add the following comment in front of the selector:

/* cssmodules-pure-ignore */
:global(#modal-backdrop) {
  ...;
}
