# CSS Modules: Values Pass arbitrary values between your module files ### Usage ```css /* colors.css */ @value primary: #BF4040; @value secondary: #1F4F7F; .text-primary { color: primary; } .text-secondary { color: secondary; } ``` ```css /* breakpoints.css */ @value small: (max-width: 599px); @value medium: (min-width: 600px) and (max-width: 959px); @value large: (min-width: 960px); ``` ```css /* my-component.css */ @value colors: "./colors.css"; @value primary, secondary from colors; @value small as bp-small, large as bp-large from "./breakpoints.css"; .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. ### Justification See [this PR](https://github.com/css-modules/css-modules-loader-core/pull/28) for more background ## License ISC ## With thanks - Mark Dalgleish - Tobias Koppers - Josh Johnston --- Glen Maddern, 2015.
