如何給Typora設置標題自動編號

注意，本文可能過期失效。

這個問題已經有很多人提供了解決的方案，這里記錄其中一種方案。

可以看看這篇知乎文章，里面告訴我們官方早就2016年提供了解決方案：Typora 標題自動編號 - 一大朵雲的文章 - 知乎 https://zhuanlan.zhihu.com/p/110257979。

如果想直接看官方給的解決方案，可以看這里：http://support.typora.io/Auto-Numbering/

你可能要知道如何在Typora中新增 css 文件：http://support.typora.io/Add-Custom-CSS/

此外，官方直接給出的方案只能為正文中的標題自動編號，如果想為側邊欄設置標題自動編號，可以看官方引用的解決方案：https://pastebin.com/XmYgBbaz

可以把上述的方案提供的css代碼放在同一個base.user.css文件中，就能同時為正文和側邊欄的標題設置自動編號。

}

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

.outline-h6>.outline-item>.outline-label:before {

}

/** 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;
}

最后要注意，上述方案提供的css默認是從一級標題開始編號的，你可以簡單修改成從二級標題開始編號，這里不再贅述。
