问题痛点

你是否在Typora中遇到过这些困扰？ ✅ 手动添加「1.1、1.2.3」编号效率低下 ✅ 调整章节顺序导致编号错乱 ✅ 无法实现「第一章、第一节」中文编号

本文将用自定义CSS代码彻底解决这些问题！

一、基础版：自动生成多级数字编号

（一）、创建CSS文件（支持所有主题）

在Typora主题目录（打开typora-设置-外观-找到主题文件夹）新建 auto-number.css，添加以下代码：

        
        
        
    
/** 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(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;
}

然后重启即可

新建一个 markdown 文档试验一下，只需要填写章节名，就会自动在章节名前添加序号

二、进阶技巧：满足特殊需求

如果你有特殊的编号需求，比如序号要是中文的，第一节…..之类

        
        
        
    
h1::before { 
  content: "第" counter(h1, cjk-ideographic) "章 ";
}
h2::before { 
  content: "第" counter(h2, cjk-ideographic) "节 ";
}

只需要修改 h:before{} 渲染的样式即可
