要實現(xiàn)中國時間秒表顯示在線顯示網(wǎng)頁，可以使用HTML、CSS和JavaScript。以下是一個簡單的示例：

創(chuàng)建一個HTML文件，例如index.html，并添加以下內(nèi)容：

<!DOCTYPE html>
<html lang="zh-CN">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>中國時間秒表</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="clock">
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <div class="hand"></div>
        <button id="start">開始</button>
    </div>
    <script src="script.js"></script>
</body>
</html>

接下來，創(chuàng)建一個名為styles.css的CSS文件，并添加以下內(nèi)容：

body {
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
    font-family: Arial, sans-serif;
}

.clock {
    display: inline-block;
    position: relative;
    transform: rotate(90deg);
}

.hand {
    display: block;
    transition: all 0.05s;
}

最后，創(chuàng)建一個名為script.js的JavaScript文件，并添加以下內(nèi)容：

document.addEventListener('DOMContentLoaded', function() {
    const clockDiv = document.getElementById('clock');
    const startButton = document.getElementById('start');
    const time = new Date();
    const hours = String(time.getHours()).padStart(2, '0');
    const minutes = String(time.getMinutes()).padStart(2, '0');
    const seconds = String(time.getSeconds()).padStart(2, '0');
    let isRunning = false;
    let intervalId;

    startButton.addEventListener('click', () => {
        if (isRunning) return;
        isRunning = true;
        clockDiv.textContent = `${hours}:${minutes}:${seconds}`;
        intervalId = setInterval(() => {
            if (isRunning) {
                hours = String(time.getHours()).padStart(2, '0');
                minutes = String(time.getMinutes()).padStart(2, '0');
                seconds = String(time.getSeconds()).padStart(2, '0');
                clockDiv.textContent = `${hours}:${minutes}:${seconds}`;
            } else {
                clearInterval(intervalId);
            }
        }, 1000);
    });
});

運行index.html文件，你將看到一個顯示當(dāng)前時間的秒表。點擊“開始”按鈕，秒表將開始每秒更新一次。
