--description--

Crea una nuova variabile sotto le altre, chiamala --building-color3 e dalle il valore #cc6699. Quindi usala come valore di background-color della classe .bb3 e aggiungi un valore di fallback pink.

--hints--

Dovresti definire una nuova variabile di proprietà chiamata --building-color3.

assert.exists(new __helpers.CSSHelp(document).isPropertyUsed('--building-color3'));

Dovresti dare a --building-color3 il valore #cc6699.

assert.equal(new __helpers.CSSHelp(document).getStyle('.bb1')?.getPropertyValue('--building-color3')?.trim(), '#cc6699');

Dovresti impostare la proprietà background-color di .bb3.

assert.exists(new __helpers.CSSHelp(document).getStyle('.bb3')?.backgroundColor);

Dovresti impostare la proprietà background-color usando la variabile --building-color3 e il fallback pink.

assert.equal(new __helpers.CSSHelp(document).getStyle('.bb3')?.backgroundColor.trim(), 'var(--building-color3, pink)');
