<body>
<!-- span的位置决定前后 -->
<!-- input-group-addon\input-group\form-control缺一不可 -->

<div class="input-group">
<!-- 前面 -->
<span class="input-group-addon">@
</span>
<input type="text" class="form-control" placeholder="Username">
</div>
<br/>

<div class="input-group">
<input type="text" class="form-control" placeholder="Username">
<span class="input-group-addon">@
</span>
</div>
<br/>
<!-- 大号 -->
<div class="input-group input-group-lg">
<span class="input-group-addon">@
</span>
<input type="text" class="form-control" placeholder="Username">
<span class="input-group-addon">qq
</span>
</div>
<br/>

<!-- form表单 form-control的效果-->
<form action="" method="post" role="form">
<div class="form-group">
<label for="username">username:</label>
<input class="form-control" id="username" name="username" type="text"><br>
</div>
<div class="form-group">
<label>password:</label>
<input class="form-control" name="password" type="text"><br>
</div>
<input type="submit" value="submit"><input type="reset" value="reset">
