Examples
// foo.css ====================
:local(.className) { background: red; }
:local .className { color: green; }
:local(.className .subClass) { color: green; }
:local .className .subClass :global(.global-class-name) { color: blue; }
// bar.css ====================
@use .className as .basicClassName from './foo';
.basicClassName { color: red; }
.className { color: blue; }
Becomes
// foo.css ====================
._className_wo9uw_1 { background: red; }
._className_wo9uw_1 { color: green; }
._className_wo9uw_1 ._subClass_wo9uw_3 { color: green; }
._className_wo9uw_1 ._subClass_wo9uw_3 .global-class-name { color: blue; }
// bar.css ====================
._className_wo9uw_1 { color: red; }
._className_c6lnr_1 { color: blue; }
Note that this postcss-modular
plugin can use classNames from different files with the rule @use
, even if they are localized. This makes theming possible and reduces code.
Features
@use
@use .className[ as .label][, ...] from '<filepath>'
Points to the same className from other file, thus using the same hashed name.
Note: If the option useNoImported
is equals 'error'
the referenced file must be proccessed before the referencer. With ignore
value, it will just work fine.
:global
:global .className
or :global(.className .subClassName)
Creates a global scope so the classNames won't be hashed
:local
Creates a local scope so the classNames will be hashed
Note: The option modules defines the default scope of the file. true
= local, false
= global
