Typora自动编号功能——最强版

/* 正文标题区: #write */
/* [TOC]目录树区: .md-toc-content */
/* 侧边栏的目录大纲区: .sidebar-content */

/** 
 * 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。
