What are the advanced features of Markdown?

Advanced Markdown features include tables, footnotes, definition lists, task lists, math equations, diagrams, custom containers, attributes, and extended syntax like strikethrough and highlighting.

How do I create tables in Markdown?

To create tables in Markdown, use pipe symbols (|) to separate columns and hyphens (-) to create the header row. For example: |Header 1|Header 2| followed by |--------|--------| and then |Cell 1|Cell 2|. You can align columns using colons in the header separator row.

Can I include math equations in Markdown?

Yes, you can include math equations in Markdown using LaTeX syntax. Inline equations are wrapped in single dollar signs ($equation$) while block equations use double dollar signs ($$equation$$). Many Markdown processors support MathJax or KaTeX for rendering.

How do I create diagrams in Markdown?

You can create diagrams in Markdown using specialized syntax like Mermaid or PlantUML. These are included in code blocks with the appropriate language identifier, such as ```mermaid or ```plantuml, followed by the diagram code.

What are Markdown custom containers?

Custom containers are extended Markdown syntax that allow you to create specialized blocks like notes, warnings, or tips. They typically use the ::: syntax followed by a container type, content, and closing :::. They're useful for highlighting important information.

How do I add footnotes in Markdown?

To add footnotes in Markdown, use [^label] in the text where you want the footnote reference, then define the footnote content with [^label]: Your footnote text at the bottom of the document. The label can be any combination of characters without spaces.
