### 实现2025跨年页面效果的HTML、CSS和JavaScript代码
#### HTML部分
创建基本的HTML结构来定义页面的内容布局。
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Happy New Year 2025</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<h1>Welcome to the Future!</h1>
<p id="countdown">Days Until New Year's Day:</p>
<div id="clock"></div>
<footer>© Happy New Year 2025</footer>
</div>
<script src="script.js"></script>
</body>
</html>
```
此段落描述了如何利用HTML建立网页内容和结构[^1]。
#### CSS样式表
通过CSS设置页面外观,使页面具有吸引力并适应不同设备屏幕尺寸。
```css
/* styles.css */
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body, html {
height: 100%;
font-family: Arial, sans-serif;
background-color: #f7eac9;
display: flex;
justify-content: center;
align-items: center;
}
.container {
text-align: center;
}
h1 {
color: #d63b3c;
font-size: 4em;
}
#countdown {
font-weight: bold;
font-size: 2em;
color: #ffcc00;
}
#clock {
margin-top: 20px;
font-size: 3em;
color: white;
letter-spacing: 5px;
}
```
这部分展示了怎样运用CSS负责网页的视觉设计。
#### JavaScript脚本
编写JavaScript逻辑以计算距离新年还有多少天,并实时更新倒计时时钟显示。
```javascript
// script.js
function updateCountdown() {
const newYearDate = new Date('January 1, 2025');
let currentDate = new Date();
if (currentDate >= newYearDate) {
document.getElementById('countdown').innerText = "HAPPY NEW YEAR!";
document.getElementById('clock').innerText = "";
return;
}
let diffInTime = newYearDate.getTime() - currentDate.getTime();
let daysUntilNewYear = Math.floor(diffInTime / (1000 * 60 * 60 * 24));
document.getElementById('countdown').innerText = `Only ${daysUntilNewYear} Days Left!`;
setTimeout(updateCountdown, 1000);
}
updateCountdown();
```
上述代码说明了如何借助JavaScript添加动态交互功能。
