# --description--
|
|
|
|
Para crear una variable CSS, solo tienes que darle un nombre que comience con dos guiones (--) y asignarle un valor, como se muestra a continuación:
|
|
|
|
```css
|
|
--penguin-skin: gray;
|
|
```
|
|
|
|
Esto creará una variable llamada `--penguin-skin` y le asignará el valor `gray`. Ahora puedes usar esa variable en cualquier otro lugar de tu código CSS para cambiar el valor de otros elementos a "gray" (gris).
|
|
|
|
# --instructions--
|
|
|
|
En la clase `penguin`, crea un nombre de variable `--penguin-skin` y asígnale el valor `gray`.
|
|
|
|
# --hints--
|
|
|
|
La clase `penguin` debe declarar la variable `--penguin-skin` y asignarle el valor `gray`.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/\.penguin\s*\{[^{}]*?--penguin-skin\s*:\s*gr[ae]y\s*;[^{}]*?\}/gi)
|
|
);
|
|
```
|
|
