Package Exports

postcss-modules-values

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (postcss-modules-values) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

CSS Modules: Values

Pass arbitrary values between your module files

Usage

/* colors.css */
@value primary: #BF4040;
@value secondary: #1F4F7F;

.text-primary {
  color: primary;
}

.text-secondary {
  color: secondary;
}

/* breakpoints.css */
@value small: (max-width: 599px);
@value medium: (min-width: 600px) and (max-width: 959px);
@value large: (min-width: 960px);

/* my-component.css */
/* alias paths for other values or composition */
@value colors: "./colors.css";
/* import multiple from a single file */
@value primary, secondary from colors;
/* make local aliases to imported values */
@value small as bp-small, large as bp-large from "./breakpoints.css";
/* value as selector name */
@value selectorValue: secondary-color;

.selectorValue {
  color: secondary;
}

.header {
  composes: text-primary from colors;
  box-shadow: 0 0 10px secondary;
}

@media bp-small {
  .header {
    box-shadow: 0 0 4px secondary;
  }
}
@media bp-large {
  .header {
    box-shadow: 0 0 20px secondary;
  }
}

If you are using Sass along with this PostCSS plugin, do not use the colon : in your @value definitions. It will cause Sass to crash.

Note also you can import multiple values at once but can only define one value per line.

@value a: b, c: d; /* defines a as "b, c: d" */
