HTML+CSS制作炫彩的数字时钟
效果图如下：

<!DOCTYPE html>
<html lang="zh-Hans">

    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>数字时钟</title>
    <link rel="stylesheet" href="style.css">
</head>

<body>
    <div class="clock_box">
        <div class="clock">
            <p id="time"></p>
        </div>
    </div>
    <script>
        // 获取页面id=time的元素（P元素<p id="time">12:12:12 AM</p>）
        var time = document.querySelector("#time");

        // 定义函数传入time元素
        function up(time_el) {
            // 获取当前时间
            let date = new Date();
            // 获取时分秒
            let h = date.getHours();
            let m = date.getMinutes();
            let s = date.getSeconds();
            // 上午与下午
            let day_night = "AM";

            // 计算上午与下午
            if (h > 12) {
                h = h - 12;
                day_night = "PM";
            }

            // 如果时间小于10则前面补充0
            if (h < 10) { h = "0" + h; }
            if (m < 10) { m = "0" + m; }
            if (s < 10) { s = "0" + s; }

            // 拼接时间并且赋值给time元素的文本中，从而显示
            time_el.textContent = h + ":" + m + ":" + s + " " + day_night;

        }

        // 定时器，每秒执行一次实现更新
        setInterval(() => {
            up(time);
        }, 1000);

    </script>
</body>

</html>
