--description--

你可以使用 CSS 里的 width 属性来指定元素的宽度。 属性值可以是相对单位(比如 em),绝对单位(比如 px),或者包含块(父元素)宽度的百分比。 下面这段代码可以把图片的宽度设置为 220px

img {
  width: 220px;
}

--instructions--

为卡片元素添加 width 属性,并将它的宽度设置为 245px。 使用 fullCard class 来选择卡片元素。

--hints--

应使用 fullCard class 选择器将卡片的 width 属性值设置为 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'
);
