一官方说明

在这里插入图片描述

To achieve this, add the following to your base.user.css or [theme].user.css in the theme folder.

/** 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;

4.1、Auto-Numbering in TOC
If you want TOC entities to be displayed auto-numbered, you could try http://pastebin.com/NYugSbXk posted by a Typora user.

/*************************************** Header Counters in TOC**************************************//* No link underlines in TOC */
.md-toc-inner {text-decoration: none;
}.md-toc-content {counter-reset: h1toc
}.md-toc-h1 {margin-left: 0;font-size: 1.5rem;counter-reset: h2toc

4.2、Auto-Numbering Outline panel
To show auto-numbering in Typora’s Outline panel, disable the collapsable outline panel in the preferences panel and then try https://pastebin.com/XmYgBbaz.

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