Description

CSS 的width属性可以控制元素的宽度。图片的width宽度类似于字体的px（像素)值。假如，你想创建一个叫larger-image的 CSS class 来控制 HTML 元素的宽度为 500px，我们可以这样做：

<style>
  .larger-image {
    width: 500px;
  }
</style>

Instructions

创建一个smaller-image的 CSS class，设置图片的宽度为 100px。 注意：
由于不同浏览器的差异性，你可能需要将浏览器缩放到 100% 来通过该挑战。

Tests

tests:
  - text: '<code>img</code>元素应该含有<code>smaller-image</code> class。'
    testString: assert($("img[src='https://bit.ly/fcc-relaxing-cat']").attr('class') === "smaller-image");
  - text: '图片宽度应为 100px（像素），且浏览器缩放应为默认 100%。'
    testString: assert($("img").width() === 100);
