## Description
|
|||
|
|
<section id='description'>
|
|||
|
|
和 <code>width</code> 属性类似，你可以使用 CSS 里面的 <code>height</code> 属性来指定元素的高度。下面这个例子把图片的高度设置为 20px：
|
|||
|
|
|
|||
|
|
```css
|
|||
|
|
img {
|
|||
|
|
height: 20px;
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
</section>
|
|||
|
|
|
|||
|
|
## Instructions
|
|||
|
|
<section id='instructions'>
|
|||
|
|
给 <code>h4</code> 标签添加 <code>height</code> 属性并设置值为 25px。
|
|||
|
|
<strong>注意：</strong> 可能需要将浏览器的缩放比调整为 100% 才能通过这一挑战。

tests:
|
|||
|
|
- text: '你应该设置 <code>h4</code> 的 <code>height</code> 属性，使其值为 <code>25px</code>。'
|
|||
|
testString: assert(Math.round(document.querySelector('h4').getBoundingClientRect().height) === 25 && /h4{\S*height:25px(;\S*}|})/.test($('style').text().replace(/\s/g ,'')));
|
