我们在div里放一个img发现
在html和html5中div的长宽是不同的后者的高度要超过几个像素。
比如说下面这个是html的。
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
*{
margin: 0px;
padding: 0px;
}
</style>
</head>
<body>
<div>
<img src="/Users/smyhvae/Dropbox/img/20170813_1143.jpg" alt="">
</div>
</body>
</html>
```
