This article explains how to enable HTML code rendering in Hugo. By adding specific configurations to the config file (either config.toml or config.yaml), it is possible to insert iframe, video, and other HTML tags in articles. Without these configurations, HTML code will be automatically filtered.

To insert iframes, videos, and other tags like summary in articles, you can configure the config file.

If it is config.toml, add the following configuration:

[markup]
  [markup.goldmark]
    [markup.goldmark.renderer]
      unsafe = true

If it is config.yaml, add the following configuration:

markup:
  goldmark:
    renderer:
      unsafe: true

This way, you can insert iframes, videos, and other tags like summary in articles.

Otherwise, the following comment will be displayed and HTML code will be automatically filtered.
