bootstrap表单

向父 <form> 元素添加 role="form"。
把标签和控件放在一个带有 class .form-group 的 <div> 中。这是获取最佳间距所必需的。
向所有的文本元素 <input>、<textarea> 和 <select> 添加 class ="form-control" 。 

<form role="form"           表单标记
	<div class="form-group"       表单渲染
    <p class="form-control-static"    静态文字渲染
		<input class="form-control"       动态输入渲染

bs3-form  使用intellij的bootstrap插件就可以生成

<form class="form-horizontal" role="form">
  <div class="form-group">
    <label for="firstname" class="col-sm-2 control-label">名字</label>
    <div class="col-sm-10">
      <input type="text" class="form-control" id="firstname" placeholder="请输入名字">
    </div>
  </div>
  <div class="form-group">
    <label for="lastname" class="col-sm-2 control-label">姓</label>
    <div class="col-sm-10">
      <input type="text" class="form-control" id="lastname" placeholder="请输入姓">
    </div>
