用bootstrap,例如

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>个人站点</title>
        <!-- 新 Bootstrap5 核心 CSS 文件 -->
        <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css">

        <!--  popper.min.js 用于弹窗、提示、下拉菜单 -->
        <script src="https://cdn.staticfile.org/popper.js/2.9.3/umd/popper.min.js"></script>

        <!-- 最新的 Bootstrap5 核心 JavaScript 文件 -->
        <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.min.js"></script>
    </head>

用某些框架的栅栏划分区域，或者width都换成百分比来取值；
这样就会自适应屏幕大小
