Markdown

As explained in DuckDB in Action

Markdown is a lightweight markup language that represents formatted text using plain-text syntax and can be converted to HTML.

Markdown is a lightweight markup language that uses readable plain-text syntax and converts it into structurally valid HTML. Streamlit renders it through st.markdown, making it useful for headings and formatted app content. section 9.1.3

Formatting a Streamlit comparison

A Streamlit app uses st.markdown to place two player names at opposite sides of a layout and show their win count between them. Custom HTML inside the Markdown requires unsafe_allow_html=True; a separate Markdown heading labels the matches table.

How DuckDB in Action covers it

What you can do after
