css怎么设置单元格的高度宽度自适应

在css中由于height是不固定的,所以不能直接使用height值。因此转换思路使用width值来实现正方形的height赋值。所以理论上只要能够将宽度属性应用在高度属性的方法都可以。

所以我们可以用到vw单位,1 个 vw 相当于页面宽度的 1%,比如页面宽度是 1000px,那么 1vw就是 10px。

具体事例如下:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
    <style>
    .shiying{
  width: 30%;
  height: 30vw;
}
    </style>
<table class="shiying" border="1">
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
</table>
</body>
</html>
