#Footer & ICP Beian

The site footer appears at the bottom of every page. ModernDuang gives you control over copyright information, social media links, custom HTML content, and ICP record-filing (Beian) numbers required for websites hosted in mainland China.

#Configuration

The footer is configured under the footer key in _config.modernduang.yml:

footer:
  since: 2024
  author: ''
  powered: true
  social:
    travelling: true
    github: true
    email: false
    custom: []
  custom: ''
  beian:
    icp: ''
    moe: ''
    chabei: ''

#Basic Footer Options

#Copyright Line

The copyright line auto-generates from since and author:

© 2024 – 2026 YourName. All rights reserved.

• The start year is taken from since
• The end year is the current year (auto-updates)
• If since equals the current year, only a single year is shown: © 2026 YourName

If author is empty, the copyright line uses the site title from Hexo's _config.yml as a fallback.

#Powered By

When powered: true, the following line appears below the copyright:

Powered by Hexo & ModernDuang

Both "Hexo" and "ModernDuang" are linked to their respective project websites.

#Footer Social Icons

The footer can display a row of social icon links, configured under footer.social:

footer:
  social:
    travelling: true
    github: true
    email: false
    custom: []

#How Icons Resolve URLs

The github and email toggles automatically pull their URLs from your profile social links (profile.social). For example, if you configured:

profile:
  social:
    - name: GitHub
      url: https://github.com/yourname
      icon: github

Then footer.social.github: true will display a GitHub icon pointing to https://github.com/yourname.

If the corresponding social entry is not found in profile.social, the icon is hidden regardless of the toggle.

#Custom Social Icons

You can add arbitrary social icons that are not tied to profile links:

footer:
  social:
    custom:
      - name: RSS
        url: /atom.xml
        icon: rss
        color: '#FF6600'
      - name: Telegram
        url: https://t.me/yourchannel
        icon: '<svg viewBox="0 0 24 24" ...>...</svg>'
        color: '#0088cc'

See the Social Icons page for the full list of 11 built-in icon names.

#Custom Footer HTML

You can inject arbitrary HTML content into the footer using the custom property:

footer:
  custom: '<p style="text-align:center; font-size:0.85em;">Hosted on <a href="https://vercel.com">Vercel</a>. All content licensed under CC BY-NC-SA 4.0.</p>'

The custom HTML is rendered below the copyright line and above the Beian information. Any valid HTML is accepted, but note that:

• Inline styles are supported
• Script tags may be stripped by Hexo's rendering engine
• The HTML is inserted raw, so be careful to close all tags

#ICP Beian (Record Filing)

If your website is hosted in mainland China, you are legally required to display an ICP (Internet Content Provider) record-filing number in the footer. ModernDuang supports three Beian formats:

footer:
  beian:
    icp: ''       # MIIT Beian
    moe: ''       # Moe Beian
    chabei: ''    # Chabei Beian

#MIIT Beian (beian.icp)

The standard MIIT (Ministry of Industry and Information Technology) ICP filing number:

beian:
  icp: "京ICP备12345678号"

Renders as:

京ICP备12345678号

The entire string is displayed as-is and linked to https://beian.miit.gov.cn/. You must include the full Beian number exactly as issued by the MIIT.

#Moe Beian (beian.moe)

The Moe ICP filing (萌ICP备), a community-managed alternative for personal websites:

beian:
  moe: "123456"

Renders as:

萌ICP备123456号

The theme automatically prepends "萌ICP备" and appends "号" to your numeric code. Official site: https://icp.gov.moe/join.php.

#Chabei Beian (beian.chabei)

The Chabei ICP filing (茶ICP备), another community Beian service:

beian:
  chabei: "123456"

Renders as:

茶ICP备123456号

The theme automatically prepends "茶ICP备" and appends "号". Official site: https://icp.redcha.cn/.

#Display Order

If multiple Beian numbers are set, they are displayed in this order:

1. MIIT (icp)
2. Moe (moe)
3. Chabei (chabei)

Each entry is separated by a vertical bar (|) divider.

#Complete Example

Here is a fully configured footer:

footer:
  since: 2023
  author: Zhang Wei
  powered: true
  social:
    travelling: true
    github: true
    email: true
    custom:
      - name: RSS
        url: /atom.xml
        icon: rss
        color: '#FF6600'
  custom: '<p>Hosted on <a href="https://vercel.com">Vercel</a> with ❤️</p>'
  beian:
    icp: "京ICP备12345678号"
    moe: "123456"

This footer would render as:
