title: 创建一个 Bootstrap Row

# --description--
这次为内联元素创建一个 Bootstrap 栅格系统的 Row
`h3` 标签下方创建一个 class 属性为 `row``div` 元素。
# --hints--
`h3` 元素下应该增加一个 `div` 元素。
```js
assert(
$('div').length > 1 &&
$('div.row h3.text-primary').length == 0 &&
$('div.row + h3.text-primary').length == 0 &&
$('h3.text-primary + div.row').length > 0
);
```
`div` 元素的 class 属性应为 `row`
```js
assert($('div').hasClass('row'));
```
`row div` 应该内嵌于 `container-fluid div`
```js
assert($('div.container-fluid div.row').length > 0);
```
确保所有 `div` 元素都有一个闭合标签。
```js
assert(
code.match(/<\/div>/g) &&
code.match(/<div/g) &&
code.match(/<\/div>/g).length === code.match(/<div/g).length
);
```
