---|
| 27 |
|
---|
| 28 | ```css
|
---|
| 29 | /* my-component.css */
|
---|
| 30 | /* alias paths for other values or composition */
|
---|
| 31 | @value colors: "./colors.css";
|
---|
| 32 | /* import multiple from a single file */
|
---|
| 33 | @value primary, secondary from colors;
|
---|
| 34 | /* make local aliases to imported values */
|
---|
| 35 | @value small as bp-small, large as bp-large from "./breakpoints.css";
|
---|
| 36 | /* value as selector name */
|
---|
| 37 | @value selectorValue: secondary-color;
|
---|
| 38 |
|
---|
| 39 | .selectorValue {
|
---|
| 40 | color: secondary;
|
---|
| 41 | }
|
---|
| 42 |
|
---|
| 43 | .header {
|
---|
| 44 | composes: text-primary from colors;
|
---|
| 45 | box-shadow: 0 0 10px secondary;
|
---|
| 46 | }
|
---|
| 47 |
|
---|
| 48 | @media bp-small {
|
---|
| 49 | .header {
|
---|
| 50 | box-shadow: 0 0 4px secondary;
|
---|
| 51 | }
|
---|
| 52 | }
|
---|
| 53 | @media bp-large {
|
---|
| 54 | .header {
|
---|
| 55 | box-shadow: 0 0 20px secondary;
|
---|
| 56 | }
|

| 60 | **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.
|
---|
| 61 |
|
---|
| 62 | Note also you can _import_ multiple values at once but can only _define_ one value per line.
|
---|
| 63 |
|
---|
| 64 | ```css
|
---|
| 65 | @value a: b, c: d; /* defines a as "b, c: d" */
|
---|
| 66 | ```
