--description--

border-radius 屬性最多接受四個值來使左上角、右上角、右下角和左下角變爲圓角。

.three 的左上角圓角設爲 30 像素,右上角圓角設爲 25 像素,右下角圓角設爲 60 像素,左下角圓角設爲 12 像素。

--hints--

應該將 border-radius 屬性設置爲 30px 25px 60px 12px

const hasBorderRadius = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style['border-radius'] === '30px 25px 60px 12px');
assert(hasBorderRadius);

.three 元素的 border-radius 值應爲 30px 25px 60px 12px

const threeBorderRadius = new __helpers.CSSHelp(document).getStyle('.three')?.getPropertyValue('border-radius');
assert(threeBorderRadius === '30px 25px 60px 12px');
