# --description--
让我们来为 Cat Photo App 做一个导航吧,把标题和惬意的猫咪图片放在同一行。
记住,由于 Bootstrap 使用了响应式栅格系统,使得我们可以很方便的放置元素并为元素指定相对的宽度。大部分的 Bootstrap 的 class 都能用在 `div` 元素上。
把我们的第一张图片和 `h2` 元素用一个简单的 `<div class="row">` 元素包裹起来。再用 `<div class="col-xs-8">` 包裹我们的 `h2` 元素,用 `<div class="col-xs-4">` 包裹我们的图片,这样它们就能位于同一行了。
注意现在图片是否与文字大小一致呢?
# --hints--
`h2` 元素和最上方的 `img` 元素应该一起内嵌于具有 `row` class 的 `div` 元素内。
```js
assert($('div.row:has(h2)').length > 0 && $('div.row:has(img)').length > 0);
```
最上方的 `img` 元素应该内嵌于含有 `col-xs-4` class 的 `div` 元素中。
```js
assert(
$('div.col-xs-4:has(img)').length > 0 &&
$('div.col-xs-4:has(div)').length === 0
);
```
`h2` 元素应该内嵌于含有 `col-xs-8` class的 `div` 元素中。
```js
assert(
$('div.col-xs-8:has(h2)').length > 0 &&
$('div.col-xs-8:has(div)').length === 0
);
```
确保每一个 `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
);
```
