HTML之拜年/跨年APP（改进版）

二：效果

三：页面分析/开发逻辑

1.页面详细分析：

（1）页面标题为"拜年跨年倒计时"，表明该页面的主要功能是提供两个倒计时：一个用于拜年，另一个用于跨年。

（2）页面显示了两个倒计时的时间：距离2025年拜年还有8天14时13分23秒，距离2026年跨年还有345天14时13分23秒。

（3）页面底部显示了版权信息，表明该页面是由宁夏线上海原编程培训中心/研发/开发工作室开发的。

2.开发逻辑：

首先，需要获取当前的日期和时间。

然后，计算距离2025年拜年和2026年跨年的剩余时间。

将剩余时间以天、小时、分钟和秒的形式显示在页面上。

最后，更新版权信息，显示开发者的名称和联系方式。
