html - 如何将分组输入与对齐表单结合起来？

Question

来自Pure CSS我要合并aligned forms :

<link href="https://cdnjs.cloudflare.com/ajax/libs/pure/0.6.0/forms-min.css" rel="stylesheet" />
<form class="pure-form pure-form-aligned">
  <fieldset>
    <div class="pure-control-group">
      <label for="name">Username</label>
      <input id="name" type="text" placeholder="Username">
    </div>

    <div class="pure-control-group">
      <label for="password">Password</label>
      <input id="password" type="password" placeholder="Password">
    </div>

    <div class="pure-control-group">
      <label for="email">Email</label>
      <input id="email" type="email" placeholder="Email">
    </div>
  </fieldset>
</form>

与grouped inputs :

<link href="https://cdnjs.cloudflare.com/ajax/libs/pure/0.6.0/forms-min.css" rel="stylesheet" />
<form class="pure-form">
  <fieldset class="pure-group">
    <input type="text" placeholder="Username">
    <input type="text" placeholder="Password">
    <input type="email" placeholder="Email">
  </fieldset>
</form>

以便堆叠输入，同时仍然允许将水平对齐的标签放置在左侧。怎样才能达到这样的效果呢？

我通过将分组输入样式应用到修改后的对齐表单布局来找到解决方案:

.pure-form-aligned .pure-group .pure-control-group {
  margin: 0;
}
.pure-form.pure-form-aligned .pure-group .pure-control-group input {
  display: inline-block;
  position: relative;
  margin: 0 0 -1px;
  border-radius: 0;
  top: -1px;
}
.pure-form-aligned .pure-group .pure-control-group:first-child input {
  top: 1px;
  border-radius: 4px 4px 0 0;
  margin: 0;
}
.pure-form-aligned .pure-group .pure-control-group:last-child input {
  top: -2px;
  border-radius: 0 0 4px 4px;
  margin: 0;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/pure/0.6.0/forms-min.css" rel="stylesheet" />
<form class="pure-form pure-form-aligned">
  <fieldset class="pure-group">
    <div class="pure-control-group">
      <label for="name">Username</label>
      <input id="name" type="text" placeholder="Username">
    </div>

    <div class="pure-control-group">
      <label for="password">Password</label>
      <input id="password" type="password" placeholder="Password">
    </div>

    <div class="pure-control-group">
      <label for="email">Email</label>
      <input id="email" type="email" placeholder="Email">
    </div>
  </fieldset>
</form>
