# --description--
|
||
|
||
`div` 元素也叫 Content Division Element（内容划分元素）元素，是一个包裹其他元素的通用容器。
|
||
|
||
它也是 HTML 中出现频率最高的元素。
|
||
|
||
和其他普通元素一样，你可以用 `<div>` 来标记一个 `div` 元素的开始，用 `</div>` 来标记一个 `div` 元素的结束。
|
||
|
||
# --instructions--
|
||
|
||
请把无序列表、有序列表和段落都嵌套进同一个 `div` 元素。
|
||
|
||
提示：你可以在第一个 `<p>` 之前插入 `div` 开始标记，在 `</ol>` 之后插入 `div` 结束标签。这样，所有的列表都会位于 `div` 之内。
|
||
|
||
# --hints--
|
||
|
||
所有的 `p` 元素都应嵌套在 `div` 元素中。
|
||
|
||
```js
|
||
assert($('div').children('p').length > 1);
|
||
```
|
||
|
||
所有的 `ul` 元素都应嵌套在 `div` 元素中。
|
||
|
||
```js
|
||
assert($('div').children('ul').length > 0);
|
||
```
|
||
|
||
所有的 `ol` 元素都应嵌套在 `div` 元素中。
|
||
|
||
```js
|
||
assert($('div').children('ol').length > 0);
|
||
```
|
||
|
||
`div` 元素应有结束标签。
|
||
|
||
```js
|
||
assert(
|
||
code.match(/<\/div>/g) &&
|
||
code.match(/<\/div>/g).length === code.match(/<div>/g).length
|
||
);
|
||
```
