Typora自动编号的具体操作

概述

在使用typora写比较长的文章时，需要给章节编号，方便区分层次。如果手动编号，一旦章节顺序改变，很多章节的编号都需要一一手动修改，极其麻烦。

typora官方提供了自动编号的方法：https://support.typora.io/auto-numbering/。本文将对官方提供的方法，以及简单改进进行介绍。

原理

这个方法的原理是，typora基于浏览器开发（使用快捷键shift+f12可以打开开发者工具）。因此，可以利用css实现自动编号。

具体操作

打开typora -> 文件 -> 偏好设置 -> 外观 -> 打开主题文件夹。在主题文件夹下新建文件ba.ur.css。将https://support.typora.io/auto-numbering/中提供的三份代码（分别实现文章内容自动编号、toc自动编号、侧边栏大纲自动编号）复制到ba.ur.css中。重启typora。

改进

官方提供的代码会对一级标题进行编号，但实际写文章时，一级标题往往是文章标题，无需编号，因此，我对代码进行了简单修改。下面是修改后的代码：

文章内容自动编号：

/** initialize css counter */h1 {    counter-ret: h2}h2 {    counter-ret: h3}h3 {    counter-ret: h我爱春季作文600字初中4}h4 {    counter-ret: h5}h5 {    counter-ret: h6}/** put counter result into headings */#write h2:before {    counter-increment: h2;    content: counter(h2) ". "}#write h3:before,h3.md-focus.md-heading:before /** override the default style for focud headings */ {    counter-increment: h3;    content: counter(h2) "." counter(h3) ". "}#write h4:before,h4.md-focus.md-heading:before {    counter-increment: h4;    content: counter(h2) "." counter(h3) "." counter(h4) ". "}#write h5:before,h5.md-focus.md-heading:before {    counter-increment: h5;    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) ". "}#write h6:before,h6.md-focus.md-heading:before {    counter-increment: h6;    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) "." counter(h6) ". "}/** override the default style for focud headings */#write>h3.md-focus:before,#write>管理者培训;h4.md-focus:before,#write>h5.md-focus:before,#write>h6.md-focus:before,h3.md-focus:before,h4.md-focus:before,h5.md-focus:before,h6.md-focus:before {    color: inherit;    border: inherit;    border-radius: inherit;    position: inherit;    left:initial;    float: none;    top:initial;    font-size: inherit;    padding-left: inherit;    padding-right: inherit;    vertical-align: inherit;    font-weight: inherit;    line-height: inherit;}

toc自动编号：

/* no link underlines in toc */.md-toc-inner {    text-decoration: none;} .md-经典金句toc-h1 {    margin-left: 0;    font-size: 1.5rem;    counter-ret: h2toc} .md-toc-h2 {    font-size: 1.1rem;    margin-left: 2rem;    counter-ret: h3toc} .md-toc-h3 {    margin-left: 3rem;    font-si含有动物的四字词语ze: .9rem;    counter-ret: h4toc} .md-toc-h4 {    margin-left: 4rem;    font-size: .85rem;    counter-ret: h5toc} .md-toc-h5 {    margin-left: 5rem;    font-size: .8rem;    counter-ret: h6toc} .md-toc-h6 {    margin-left: 6rem;    font-size: .75rem;} .md-toc-h2:before {    color: black;    counter-increment: h2toc;    content: counter(h2toc) ". "} .md-toc-h2 .md-toc-inner {    margin-left: 0;} .md-toc-h3:before {    color: black;    counter-increment: h3toc;    content: counter(h2toc) ". " counter(h3toc) ". "} .md-toc-h3 .md-toc-inner {    margin-left: 0;} .md-toc-h4:before {    color: black;    counter-increment: h4toc;    content: c我又没说你ounter(h2toc) ". " counter(h3toc) ". " counter(h4toc) ". "} .md-toc-h4 .md-toc-inner {    margin-left: 0;} .md-toc-h5:before {    color: black;    counter-increment: h5toc;    content: counter(h2toc) ". " counter(h3toc) ". " counter(h4toc) ". " counter(h5toc) ". "} .md-toc-h5 .md-toc-inner {    margin-left: 0;} .md-toc-h6:before {    color: black;    counter-increment: h6toc;    content: counter(h2toc) ". " counter(h3toc) ". " counter(h4toc) ". " counter(h5toc) ". " counter(h6toc) ". "} .md-toc-h6 .md-toc-inner {    margin-left: 0;} 

侧边栏大纲自动编号：

.outline-h1 {    counter-ret: h2} .outline-h2 {    counter-ret: h3} .outline-h3 {    counter-ret: h4} .outline-h4 {    counter-ret: h5} .outline-h5 {    counter-ret: h6} .outline-h2>.outline-item>.outline-label:before {    counter-increment: h2;    content: counter(h2) ". "} .outline-h3>.outline-item>.outline-label:before {    counter-increment: h3;    content: counter(h2) "." counter(h3) ". "} .outline-h4>.outline-item>.outline-label:before {    counter-increment: h4;    content: counter(h2) "." counter(h3) "." counter(h4) ". "} .outline-h5>.outline-item>.outline-label:before {    counter-increment: h5;    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) ". "} .outline-h6>.outline-item>.outline-label:before {    counter-increment: h6;    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) "." counter(h6) ". "}
