html根字体设置成很大的值后， 包裹了行内元素的div莫名变高是什么原因？

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Document</title>

    <style>
    html {
        font-size: 100px;
    }
    span {
        font-size: 12px;
        line-height: 12;
    }
    </style>
</head>
<body>
    <div>
    <span>dsflfij</span>
    </div>
</body>
</html>

    After setting the html root font to a very large value, why does the div that wraps the inline elements become inexplicably taller? -PHP Chinese website Q&A-After setting the HTML root font to a very large value, why does the div that wraps the inline elements become inexplicably taller? -PHP Chinese website Q&A

    因为font-size可继承，你这样写了后div的font-size也变大了。

    并且需要注意的一点line-height里面 12 ！= 12px,详情百度一下差异
