--description--

你可以使用 CSS 裏的 width 屬性來指定元素的寬度。屬性值可以是相對單位（比如 em），絕對單位（比如 px），或者包含塊（父元素）寬度的百分比。下面這段代碼可以把圖片的寬度設置爲 220px：

img {
  width: 220px;
}

--instructions--

爲卡片元素添加 width 屬性，並將它的寬度設置爲 245px。使用 fullCard class 來選擇卡片元素。

--hints--

應使用 fullCard class 選擇器將卡片的 width 屬性值設置爲 245px。

const fullCard = code.match(/\.fullCard\s*{[\s\S]+?[^}]}/g);
assert(
  fullCard &&
    /width\s*:\s*245px\s*(;|})/gi.test(fullCard[0]) &&
    $('.fullCard').css('maxWidth') === 'none'
);
