silverbullet/website/Markdown/Code Widgets.md

Code widgets are a SilverBullet-specific Markdown/Extensions to Markdown. Technically, it’s not an extension — it just gives new meaning to markdown’s native fenced code blocks — code blocks that start with a triple backtick, specifying a programming language.

Currently, SilverBullet provides a few code widgets out of the box:

• toc: Table of Contents
• query: Live Queries
• template: Live Templates
• embed
• markdown

In addition, plugs like Plugs/KaTeX and Plugs/Mermaid add additional ones.

embed

This allows you to embed internet content into your page inside of an iframe. This is useful to embed youtube videos or other websites. and a YouTube video:

url: https://youtu.be/BbNbZgOwB-Y

Note, there is specific support for YouTube videos — it automatically sets the width and height, and replaces the URL with an embed URL.

The body of an embed block is written in YAML and supports the following attributes:

• url (mandatory): the URL of the content to embed
• height (optional): the height of the embedded page in pixels
• width (optional): the width of the embedded page in pixels
