# 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 */
|
||
|
|
/* 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";
|
||
|
|
|
||
|
|
.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.
|
||
|
|
|
||
|
|
```css
|
||
|
|
@value a: b, c: d; /* defines a as "b, c: d" */
|
||
|
|
```
|
||
|
|
|
||
|
|
