试试下面的代码：

＆＃13;

html, body{
    width: 100%;
    height: 100%;
    padding: 0;
    margin: 0;
}
.container{
    width:100%;
    height: 100%;
    margin: 0;
    position: absolute;
    background: rgba(220,220,220, .5);
}

.modal{
    position: relative;
    top: 40%;
    margin: 0 auto;
    height: 100px;
    width: 150px;
    background: white;
    border: 1px solid #aaa;
}
p{
    margin: 0;
}

＆＃13;

<div class='container'>
    <div class='modal'>Modal window</div>
</div>
<p> other content</p>

＆＃13;

尝试使用绝对定位的容器div和具有实际内容的子div。我添加了内容其他内容的段落以说明效果

怎么弹出一个？
