【CSS Snippet】时间轴

将如下代码保存到 .obsidian/snippets/TimeLine.css 文件中（自行创建文件），然后在 Obsidian 设置——外观——代码片段中开启。即可使用 timeline 类型 callouts 创建这种堆叠卡片了。

上面示例的 callout 代码如下，供参考：

> [!timeline] 就是展示这样的时间线
> - **2024-05-01** *00:00* 就是开始放假吧
> - *05:45* 我是想晚点起的，奈何睡不着了
> - *06:30* 啊，咖啡啊，真的是续命的呢~
> - **2024-05-02** *08:00* 其实这就是个无序列表
> - **日期啦** 列表项最开始的加粗内容作为日期
> - *时间啦* 列表项最开始的斜体内容作为时间显示
> - 反正日期和时间都省略也不是不行
