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 a /* cssmodules-pure-ignore */ comment in front of the selector:

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

or by adding a /* cssmodules-pure-no-check */ comment at the top of a file to disable this check for the whole file:

/* cssmodules-pure-no-check */
:global(#modal-backdrop) {
 ...;
}
:global(#my-id) {
 ...;
}
