## Description
|
|||
|
|
<section id="description">使用CSS响应图像实际上非常简单。而不是对元素应用绝对宽度： <code>img { width: 720px; }</code>您可以使用： <blockquote> img { <br>最大宽度：100％; <br>显示：块; <br>身高：自动; <br> } </blockquote> 100％的<code>max-width</code>属性会缩放图像以适合其容器的宽度，但图像的拉伸宽度不会超过其原始宽度。将<code>display</code>属性设置为block会将图像从内联元素（默认值）更改为其自身行上的块元素。 auto的<code>height</code>属性保持图像的原始宽高比。 </section>
|

|
|
|
|||
|
|
## Instructions
|
|||
|
|
<section id="instructions">添加<code>img</code>标记的样式规则，使其响应其容器的大小。它应该显示为块级元素，它应该适合其容器的整个宽度而不拉伸，并且它应该保持其原始的宽高比。 </section>

|
|||
|

testString: 'assert(code.match(/max-width:\s*?100%;/g), "Your <code>img</code> tag should have a <code>max-width</code> set to 100%.");'
|
|||
|
|
- text: 你的<code>img</code>标签应该有一个<code>display</code>设置阻止。
|
|||
|
|
testString: 'assert($("img").css("display") == "block", "Your <code>img</code> tag should have a <code>display</code> set to block.");'
|
|||
|
|
- text: 你的<code>img</code>标签的<code>height</code>应该设置为auto。
|
