  <div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>

<form class="form-inline">
  <div class="form-group">

    <input type="email" class="form-control" id="exampleInputEmail3" placeholder="Email">
  </div>
  <div class="form-group">
    <label class="sr-only" for="exampleInputPassword3">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword3" placeholder="Password">
  </div>
  <div class="checkbox">

  </div>
  <button type="submit" class="btn btn-default">Sign in</button>
</form>

水平排列的表单

<form class="form-horizontal">
  <div class="form-group">

    <div class="col-sm-10">
      <input type="email" class="form-control" id="inputEmail3" placeholder="Email">
    </div>
  </div>
  <div class="form-group">
    <label for="inputPassword3" class="col-sm-2 control-label">Password</label>
    <div class="col-sm-10">
      <input type="password" class="form-control" id="inputPassword3" placeholder="Password">

  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">

预定义样式
