0 18270 响应式风格的单选按钮

Description

你还可以将 Bootstrap 的 col-xs-* class 用在 form 元素上!这样我们就可以在不关心屏幕大小的情况下,将我们的单选按钮均匀的平铺在页面上。 将你的所有单选按钮放入 <div class="row"> 元素。再用 <div class="col-xs-6"> 元素包裹每一个单选按钮。 记住: 提醒一句,单选按钮是 type 为 radioinput 元素。

Instructions

Tests

tests:
  - text: 把所有的单选按钮放置于具有 <code>row</code> class 的 <code>div</code> 元素中。
    testString: assert($("div.row:has(input[type=\"radio\"])").length > 0);
  - text: 每一个单选按钮应该嵌套于 <code>div</code> 元素之中,该 <code>div</code> 元素的 class 属性为 <code>col-xs-6</code>。
    testString: assert($("div.col-xs-6:has(input[type=\"radio\"])").length > 1);
  - text: 确保所有 <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);
