为 Cat Photo App 做一个导航，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，可以很方便的把元素放到一行以及指定元素的相对宽度。大部分的 Bootstrap 的 class 都能用在 div 元素上。

把第一张图片和 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 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。

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。

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。

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。

assert(
  code.match(/<\/div>/g) &&
    code.match(/<div/g) &&
    code.match(/<\/div>/g).length === code.match(/<div/g).length
);
