title: 创建自定义标题
---
## Description
<section id='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 <code>div</code> 元素上。
把我们的第一张图片和 <code>h2</code> 元素用一个简单的 <code>&#60;div class="row"&#62;</code> 元素包裹起来。再用 <code>&#60;div class="col-xs-8"&#62;</code> 包裹我们的 <code>h2</code> 元素,用 <code>&#60;div class="col-xs-4"&#62;</code> 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?

## Tests
<section id='tests'>
```yml
tests:
- text: <code>h2</code> 元素和最上方的 <code>img</code> 元素应该一起内嵌于具有 <code>row</code> class 的 <code>div</code> 元素内。
testString: assert($("div.row:has(h2)").length > 0 && $("div.row:has(img)").length > 0);
- text: 最上方的 <code>img</code> 元素应该内嵌于含有 <code>col-xs-4</code> class 的 <code>div</code> 元素中。
testString: assert($("div.col-xs-4:has(img)").length > 0 && $("div.col-xs-4:has(div)").length === 0);
- text: <code>h2</code> 元素应该内嵌于含有 <code>col-xs-8</code> class的 <code>div</code> 元素中。
testString: assert($("div.col-xs-8:has(h2)").length > 0 && $("div.col-xs-8:has(div)").length === 0);
- text: 确保每一个 <code>div</code> 元素都有一个闭合标签。
testString: assert(code.match(/<\/div>/g) && code.match(/<div/g) && code.match(/<\/div>/g).length === code.match(/<div/g).length);
