自定义typora主题样式

1、文件 – 偏好设置 – 外观 – 主题 – 打开主题文件夹

2、将准备好的自定义样式文件base.user.css,复制粘贴到对应的步骤1的文件夹中
3、退出typora程序后，重启打开typora、测试效果

补充 base.user.css，可以根据喜好自行设置

/*base.user.css */

/** 
* 说明：
*     Typora的标题共有6级，从h1到h6。
*     我个人觉得h1级的标题太大，所以我的标题都是从h2级开始。
*     个人习惯每篇文章都有一个总标题，有一个目录，所以h2级的标题前两个都不会计数。
*     一般情况下，我虽然不使用h1级的标题，但是为了以防万一，h1级的标题前两个也都不会计数。
*     若想启用h1级标题，就取消包含“content: counter(h1) "."”项的注释，然后将包含“content: counter(h2) "."”的项注释掉即可。
*
* 要完成自动编号功能，必须借助CSS3中的如下特性：
* 计数器：counter(基准计数器)，用于计算基准计数器的值
* 计数器增量：counter-increment，设置每次增长的量
* 重置计数器：counter-reset，用于将当前标题的计数器重置到指定的基准计数器
* 子代类型选择器：nth-of-type，可以从子代中选择出同一类型元素中的指定元素
