矩形太小,它們的邊緣沒有繪畫的柔和品質。

通過將 box-shadow 設置爲 0 0 3px 3px #efb762 來增加區域並柔化 .one 的邊緣。

--hints--

應該將 box-shadow 屬性設置爲 0 0 3px 3px #efb762

const hasBoxShadow = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['box-shadow'] === 'rgb(239, 183, 98) 0px 0px 3px 3px');
assert(hasBoxShadow);

.one 元素的 box-shadow 值應爲 0 0 3px 3px #efb762

const oneShadow = new __helpers.CSSHelp(document).getStyle('.one')?.getPropertyValue('box-shadow');
assert(oneShadow === 'rgb(239, 183, 98) 0px 0px 3px 3px');
