bootstrap在input框中加入icon图标

<form class="form-horizontal">
	<div class="form-group has-feedback">
		<div class="username">
			<span class="fa fa-user-circle-o fa-2x form-control-feedback"></span>
			<input type="text" class="form-control" id="inputPassword" placeholder="用户名">
		</div>
	</div>
	<div class="form-group pwd-top has-feedback">
		<div class="password">
			<span class="fa fa-unlock-alt fa-2x form-control-feedback"></span>
				<input type="password" class="form-control" id="inputPassword" placeholder="密码">
	        </div>
	</div>
	<div class="form-group">
						
		<div class="checkbox  col-sm-4 col-md-4 col-lg-4">
			<label>
      				<input type="checkbox"> 记住密码
    			</label>	
	        </div>
		<label for="" class="col-sm-4 col-md-4 col-lg-4 control-label forget-pass"><a href="">忘记密码</a></label>	
		<label for="" class="col-sm-4 col-md-4 col-lg-4 control-label register"><a href="">注册</a></label>
	</div>
	<div class="form-group">
		<button class="btn btn-login" type="submit">登&nbsp;录</button>
	</div>
</form>

实际效果

对css样式进行修改,才能使icon图标垂直居中,然后居左
下面的line-height: 50px,因为我的input框是50px高

然后这利的left:20px 如果你不给,icon图标就是靠右对齐

/*padding-left:60px   因为图标是有一个宽度,然后图标有一个left:20px   图标的宽度34px, 估计一下  设置差不多60px, 刚好让文字不被图标遮挡*/
.form-center .username input,.form-center .password input{
	height: 50px;
	padding-left: 60px;
}


.form-control-feedback {
	line-height: 50px;
	left: 20px;
}
