--description--

Puoi usare tutti i colori che vuoi in un gradiente, in questo modo:

gradient-type(
  color1,
  color2,
  color3
);

Aggiungi un linear-gradient a .bb1d con orange come primo colore, --building-color1 come secondo e --window-color1 come terzo. Ricorda di usare il gradiente sulla proprietà background.

--hints--

Dovresti applicare una proprietà background a .bb1d.

assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('.bb1d')?.background);

Dovresti assegnare un linear-gradient alla proprietà background.

assert.include(new __helpers.CSSHelp(document).getStyle('.bb1d')?.background, 'linear-gradient');

Dovresti usare orange come primo colore nel linear-gradient.

assert.include(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(orange');

Dovresti usare --building-color1 come secondo colore nel linear-gradient.

assert.include(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(orange,var(--building-color1)');

Dovresti usare --window-color1 come terzo colore nel linear-gradient.

assert.equal(new __helpers.CSSHelp(document).getStyle('.bb1d')?.getPropVal('background', true), 'linear-gradient(orange,var(--building-color1),var(--window-color1))');
