Typora 标题自动编号

原理

​ 通过修改 Typora 主题 *.css 文件源码实现。

​ *.css 文件位置：Typora 安装目录下 themes 文件夹下，例如 D:\Typora\themes。

​ Typora 自带的几种主题

![Typora 自带主题](E:\OneDrive\GitHub\Markdown-Learning\Picture\Typora 自带主题.bmp)

​ 在该目录下分别对应，同名 *.css 主题文件。

修改方法

​ 使用 notepad++ 或其他文本编辑软件打开 *.css 文件，在文本末追加 追加代码段 中的代码，保存退出。重启软件即可。

追加代码段

/** initialize css counter */
#write {
    counter-reset: h1
}

h1 {
    counter-reset: h2
}

h2 {
    counter-reset: h3
}

h3 {
    counter-reset: h4
}

h4 {
    counter-reset: h5
}

h5 {
    counter-reset: h6
}

/** put counter result into headings */
#write h1:before {
    counter-increment: h1;
    content: counter(h1) ". "
}

#write h2:before {
    counter-increment: h2;
    content: counter(h1) "." counter(h2) ". "
}

#write h3:before,
h3.md-focus.md-heading:before /** override the default style for focused headings */ {
    counter-increment: h3;
    content: counter(h1) "." counter(h2) "." counter(h3) ". "
}

#write h4:before,
h4.md-focus.md-heading:before {
    counter-increment: h4;
    content: counter(h1) "." counter(h2) "." counter(h3) "." counter(h4) ". "
}

#write h5:before,
h5.md-focus.md-heading:before {
    counter-increment: h5;
    content: counter(h1) "." counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) ". "
}

#write h6:before,
h6.md-focus.md-heading:before {
    counter-increment: h6;
    content: counter(h1) "." counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) "." counter(h6) ". "
}

/** override the default style for focused headings */
#write>h3.md-focus:before,
#write>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;
}
