| # --description--
 | |
| 
 | |
| Le <dfn>variabili CSS</dfn> sono un modo potente per cambiare molte proprietà di stile CSS in una sola volta, cambiando un solo valore.
 | |
| 
 | |
| Segui le istruzioni qui sotto per vedere come cambiando solo tre valori puoi cambiare lo stile di molti elementi.
 | |
| 
 | |
| # --instructions--
 | |
| 
 | |
| Nella classe `penguin`, cambia il valore `black` in `gray`, il valore `gray` in `white`, e il valore `yellow` in `orange`.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| La classe `penguin` dovrebbe dichiarare la variabile `--penguin-skin` e assegnarle il valore `gray`.
 | |
| 
 | |
| ```js
 | |
| assert(
 | |
|   code.match(/.penguin\s*?{[\s\S]*--penguin-skin\s*?:\s*?gray\s*?;[\s\S]*}/gi)
 | |
| );
 | |
| ```
 | |
| 
 | |
| La classe `penguin` dovrebbe dichiarare la variabile `--penguin-belly` e assegnarle il valore `white`.
 | |
| 
 | |
| ```js
 | |
| assert(
 | |
|   code.match(/.penguin\s*?{[\s\S]*--penguin-belly\s*?:\s*?white\s*?;[\s\S]*}/gi)
 | |
| );
 | |
| ```
 | |
| 
 | |
| La classe `penguin` dovrebbe dichiarare la variabile `--penguin-beak` e assegnarle il valore `orange`.
 | |
| 
 | |
| ```js
 | |
| assert(
 | |
|   code.match(/.penguin\s*?{[\s\S]*--penguin-beak\s*?:\s*?orange\s*?;[\s\S]*}/gi)
 | |
| );
 | |
| ```
