项目中经常出现广告弹窗，记录下简单弹框写法。
基本html结构：
<div class="popBox">
<div class="popBox-mask"></div>
<div class="popBox-content">
<!-- 书写弹框内容 -->
</div>
</div>.popBox-mask{
position: fixed;
left: 0;
right: 0;
top: 0;
bottom: 0;
opacity: .6;
z-index: 999;
background-color: #000;
}
.popBox-content{
position: fixed;
left: 50%;
top: 50%;
transform: translate(-50%,-50%);
z-index: 999;
}<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

<style>
/*通用*/
.popBox-mask{
position: fixed;
left: 0;
right: 0;
top: 0;
bottom: 0;
opacity: .6;
z-index: 999;
background-color: #000;
}
.popBox-content{
position: fixed;
left: 50%;
top: 50%;
transform: translate(-50%,-50%);
z-index: 999;
}
/*各个弹框下的样式可以自己更改*/
#popBox-demo .popBox-content{
width: 600px;
height: 400px;
background-color: #fff;
text-align: center;
}
#popBox-demo p{
line-height: 400px;
margin: 0;
}
#popBox-demo .btn-close{
position: absolute;
top: 20px;
right: 20px;
}
</style>
</head>
<body>
<button onclick="showPopBox()">出现弹框</button>
<div class="popBox" id="popBox-demo" style="display:none">
<div class="popBox-mask"></div>
<div class="popBox-content">
<p>很丑的例子</p>
<a href="javascript:void(0)" class="btn-close" onclick="hidePopBox()">关闭</a>
</div>
</div>
<script>
//显示弹框

document.getElementById('popBox-demo').style.display = 'block';
}
//关闭弹框
function hidePopBox(){
document.getElementById('popBox-demo').style.display = 'none';
