.threebackground-color 改爲 #b20403

--hints--

應該將 background-color 屬性設置爲 #b20403

const hasBackground = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['background-color'] === 'rgb(178, 4, 3)');
assert(hasBackground);

.three 元素的 background-color 值應爲 #b20403

const threeBackground = new __helpers.CSSHelp(document).getStyle('.three')?.getPropertyValue('background-color');
assert(threeBackground === 'rgb(178, 4, 3)');
