### Custom menu
### See https://docs.stack.jimmycai.com/configuration/custom-menu
### To remove about, archive and search page menu item, remove `menu` field from their FrontMatter
menu:
    main:
        - identifier: home
          name: Home
          url: /
          weight: -100
          pre: home

related:
    includeNewer: true
    threshold: 60
    toLower: false
    indices:
        - name: tags
          weight: 100

        - name: categories
          weight: 200

markup:
    tableOfContents:
        endLevel: 4
        ordered: true
        startLevel: 2
    highlight:
        noClasses: false

部分文章左上角不显示返回按钮

没有 TOC 的文章不会显示。

正文开头为H1时不显示返回按钮：

修改 config.yaml，把 markup.tableOfContents.startLevel 改成 1

markup:
    tableOfContents:
        endLevel: 4
        ordered: true
        startLevel: 1

修改 DefaultContentLanguage 参数后，本地渲染按钮文字为中文，上传github渲染之后为英文，且按钮大小不一致

语言的问题应该和主题没关系，可能是上传出了问题。

按钮大小问题已经在 master 分支解决了 (#245)，但是还没发新版本，也就没有编译出最新的 CSS。

改成用 Hugo Extended 版本即可。

全部解决了，果然全都是我配置的问题:sweat_smile: 真的非常感谢帮助
