删除此内容：

.login-panel {
    margin-top: 25%; 
}

by：（参见小提琴：https://jsfiddle.net/8f4epsqh/）

.login-panel{
   margin-top: 15px!important;}
.alert-danger{
  margin-top: 15px!important;
}

                </div>
            </div>
        </div>
    </div>

你可以设置margin-top提醒（就像我一样）

Answer 2

检查这一个

https://jsfiddle.net/F86597/pq4ncrb7/1/

.alert-danger{
  margin-top: -85px!important;
  position: absolute;
}
.login-panel{
   margin-top: 100px!important;
}

伙计我为上面的问题找到了更好的解决方案，你可以调整浏览器大小没问题

.vertical-offset-100{
    padding-top:100px;
}

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div class="container">
    <div class="row vertical-offset-100">
    	<div class="col-md-4 col-md-offset-4">
		 <div class="alert alert-success">
   Incorrect username or password.
  </div>
    		<div class="panel panel-default">
			  	<div class="panel-heading">
			    	<h3 class="panel-title">Please sign in</h3>
			 	</div>
			  	<div class="panel-body">
			    	<form accept-charset="UTF-8" role="form">
                    <fieldset>
			    	  	<div class="form-group">
			    		    <input class="form-control" placeholder="E-mail" name="email" type="text">
			    		</div>
			    		<div class="form-group">
			    			<input class="form-control" placeholder="Password" name="password" type="password" value="">
			    		</div>
			    		<div class="checkbox">
			    	    	<label>
			    	    		<input name="remember" type="checkbox" value="Remember Me"> Remember Me
			    	    	</label>
			    	    </div>
						
			    		<input class="btn btn-lg btn-success btn-block" type="submit" value="Login">
			    	</fieldset>
			      	</form>
			    </div>
			</div>
		</div>
	</div>
</div>
