title: 在侧边栏添加日历和倒计时
|
||
categories: 建站手札
|
||
tags: 网站
|
||
series: webcustom
|
||
summary: 实现了一个侧边栏日历与倒计时卡片，包含以下核心功能：日历展示:显示当前日期（公历与农历）、星期、生肖、干支年份。动态生成当月日历网格，高亮当天日期。倒计时模块:距离除夕倒计时：实时计算并显示剩余天数（示例中为2026年2月16日）。进度条：分别展示本年、本月、本周的已过去进度（百分比）及剩余天数。农历支持:调用 chinese-lunar.js 库将公历转换为农历，格式化显示为“干支年+生肖年+农历月+农历日”。

突然看到某个网站侧边栏有日历和倒计时，就研究了一下，抄下来了（🤭）
|
