html - 如何对齐一组中的表单元素

问题描述

我尝试使用 md-offset-8, xs-2 但这不起作用，我需要在中心对齐所有表单字段。

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" />

<div class="col-md-8 col-md-offset-4 text-center">
  <form class="form" action="/action.php", method="POST">
    <div class="form-group row">
      <div class="col-xs-4">
        <label for="field_1">Field 1</label>
        <input class="form-control" id="field_1" type="text" name="field 1">
      </div>
      <div class="col-xs-2">
        <label for="field_2">Field 2</label>
        <input class="form-control" id="field_2" type="text" name="field 2">
      </div>
    </div>
    <div class="form-group row">
      <div class="col-xs-8">
        <label for="dataFolder">Field 3</label>
        <input class="form-control" id="field_3" type="text" name="field_3" value=text>
      </div>
    </div>
    <div class="col-md-6 text-center">
      <button type="submit" class="btn ink-reaction btn-raised btn-primary">Save</button>
    </div>
  </form>
</div>

解决方案

你的意思是这样的吗？

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" />
<div id="page" class="container">
  <div class="row">
      <div class="col-md-6 col-md-offset-3 text-center">
          <div class="form-group">
              <label for="firstName">Filed 1:</label>
              <input id="firstName" class="form-control text-center" type="text">
          </div>
          <div class="form-group">
              <label for="lastName">Filed 2:</label>
              <input id="lastName" class="form-control text-center" type="text">
              <div class="form-group">
                <label for="lastName">Filed 3:</label>
                <input id="lastName" class="form-control text-center" type="text">
              <button type="submit" class="btn ink-reaction btn-raised btn-primary">Save</button>
          </div>
      </div>
  </div>
