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
);
