准备工作

打开Typora，然后依次点击：文件→偏好设置→外观→打开主题文件夹

在该文件夹中创建base.user.css文件，内容如下，保存后重启Typora即可看到效果

Type1：从一级标题开始的

/** initialize css counter */
#write,
.sidebar-content {
    counter-reset: h1;
}

h1,
.outline-h1 {
    counter-reset: h2;
}

h2,
.outline-h2 {
    counter-reset: h3;
}

h3,
.outline-h3 {
    counter-reset: h4;
}

h4,
.outline-h4 {
    counter-reset: h5;
}

h5,
.outline-h5 {
    counter-reset: h6;
}

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

#write h2:before,
.outline-h2 > .outline-item > .outline-label: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 */
.outline-h3 > .outline-item > .outline-label:before {

}

#write h6:before,

    counter-increment: h6;
    content: counter(h1) "." counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) "." counter(h6) " ";
}

/** override the default style for focused headings */

    border-radius: inherit;
    position: inherit;
    left: initial;
