盒模型布局，隐藏内部元素，外围高度居然没有改变？求解决办法

<div class="setting">
    <div class="layout-left">left</div>
    <div class="layout-right">
        <div class="change">change</div>
        <div class="change">change</div>
        <div class="change">change</div>
        <div class="change">change</div>
        <div class="text">right</div>
        <div class="text">right</div>
        <div class="text">right</div>
        <div class="text">right</div>
    </div>
  </div>
  <p>next...</p>

  <button>click me</button>
.setting{
  display: -moz-box;
  display: -webkit-box;
  display: -ms-flexbox;
  display: box;
}
.setting > div{padding:0 20px;border:1px solid #999;}
.change{background:red;}
$('button').click(function(){
  $('.change').hide();
});
