# --description--
|
||
|
||
你可以通过把元素嵌套进 `a` 里使其变成一个链接。
|
||
|
||
如果我们要把图片嵌套进 `a` 元素， 可以这样写：
|
||
|
||
```html
|
||
<a href="#"><img src="https://cdn.freecodecamp.org/curriculum/cat-photo-app/relaxing-cat.jpg" alt="Three kittens running towards the camera."></a>
|
||
```
|
||
|
||
如果把 `a` 的 `href` 属性值设置为 `#`，创建的是一个死链接（不跳转到其他画面）。
|
||
|
||
# --instructions--
|
||
|
||
请把现存的图片嵌套进 `a`（ *锚点*）元素中。
|
||
|
||
完成后，请你把鼠标光标悬停在你的图像上， 鼠标光标将变成点击光标。 于是图片就变成了链接。
|
||
|
||
# --hints--
|
||
|
||
应将 `img` 嵌套进 `a` 元素中。
|
||
|
||
```js
|
||
assert($('a').children('img').length > 0);
|
||
```
|
||
|
||
`a` 的 `href` 属性值应为 `#`。
|
||
|
||
```js
|
||
assert(new RegExp('#').test($('a').children('img').parent().attr('href')));
|
||
```
|
||
|
||
每个 `a` 元素都应该有一个结束标签。
|
||
|
||
```js
|
||
assert(
|
||
code.match(/<\/a>/g) &&
|
||
code.match(/<a/g) &&
|
||
code.match(/<\/a>/g).length === code.match(/<a/g).length
|
||
);
|
||
```
