587d781b367417b2b2512abe 給卡片元素添加 box-shadow 0 https://scrimba.com/c/cvVZdUd 301031 add-a-box-shadow-to-a-card-like-element

--description--

box-shadow 屬性用來給元素添加陰影,該屬性值是由逗號分隔的一個或多個陰影列表。

box-shadow 屬性按順序採用以下值:

  • offset-x (陰影的水平偏移量),
  • offset-y (陰影的垂直偏移量),
  • blur-radius
  • spread-radius
  • color

其中 blur-radiusspread-radius 是可選的。

可以通過逗號分隔每個 box-shadow 元素的屬性來添加多個 box-shadow。

如下爲添加了模糊效果的例子,它使用了透明度較高的黑色作爲陰影:

box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);

--instructions--

元素現在有一個 thumbnail id。 在這個選擇器中,使用上面的示例 CSS 值在卡片上加一個 box-shadow

--hints--

應該給 id 爲 thumbnail 的元素添加 box-shadow 屬性。

assert(code.match(/#thumbnail\s*?{\s*?box-shadow/g));

box-shadow 屬性值應該是題目說明中指定的 CSS 值。

assert(
  code.match(
    /box-shadow:\s*?0\s+?10px\s+?20px\s+?rgba\(\s*?0\s*?,\s*?0\s*?,\s*?0\s*?,\s*?0?\.19\)\s*?,\s*?0\s+?6px\s+?6px\s+?rgba\(\s*?0\s*?,\s*?0\s*?,\s*?0\s*?,\s*?0?\.23\)/gi
  )
);
