## Description
|
|||
|
|
<section id="description"> CSS有一个名为<code>width</code>的属性，用于控制元素的宽度。就像字体一样，我们将使用<code>px</code> （像素）来指定图像的宽度。例如，如果我们想要创建一个名为<code>larger-image</code>的CSS类，它给HTML元素的宽度为500像素，我们将使用： <blockquote> <风格> <br> .larger-image { <br>宽度：500px; <br> } <br> </样式> </blockquote></section>
|
|||
|
|
|
|||
|
|
## Instructions
|
|||
|
|
<section id="instructions">创建一个名为<code>smaller-image</code>的类，并使用它来调整图像大小，使其只有100像素宽。 <strong>注意</strong> <br>由于浏览器实现的差异，您可能需要100％缩放才能通过此挑战的测试。 </section>

## Tests

<section id='tests'>

|
|
|||
|
|
```yml
|
|||
|
|
tests:
|
|||
|
|
- text: 您的<code>img</code>元素应该具有<code>smaller-image</code>类。
|
|||
|
|
testString: 'assert($("img[src="https://bit.ly/fcc-relaxing-cat"]").attr("class") === "smaller-image", "Your <code>img</code> element should have the class <code>smaller-image</code>.");'
|
|||
|
|
- text: 您的图片应为100像素宽。浏览器缩放应为100％。
|
|||
|
|
testString: 'assert($("img").width() === 100, "Your image should be 100 pixels wide. Browser zoom should be at 100%.");'
