创建一个简单的剩余时间倒计时 HTML 代码,通常会结合 JavaScript 来动态更新时间。以下是一个基本的例子:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>剩余时间倒计时</title>
</head>
<body>
<div id="countdown">00:00:00</div>
<script>
// 假设你有一个结束时间(例如,服务器返回的时间)
const endTime = new Date("2023-07-01T12:00:00");
function countdown() {
const now = new Date();
const difference = endTime - now;
const days = Math.floor(difference / (1000 * 60 * 60 * 24));
const hours = Math.floor((difference % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
const minutes = Math.floor((difference % (1000 * 60 * 60)) / (1000 * 60));
const seconds = Math.floor((difference % (1000 * 60)) / 1000);
document.getElementById('countdown').textContent = `${days.toString().padStart(2, '0')}:${hours.toString().padStart(2, '0')}:${minutes.toString().padStart(2, '0')}:${seconds.toString().padStart(2, '0')}`;
// 每秒更新
if (difference > 0) {
setTimeout(countdown, 1000);
}
}
// 开始倒计时
countdown();
</script>
</body>
</html>
```
