(Ruby) Markdown to HTML - Full Document, ChatGPT Theme

See more Markdown Examples

Demonstrates how to convert a complete Markdown document to HTML using the pre-defined "ChatGPT" theme. The "ChatGPT" theme produces a full HTML document including:

Document Type Declaration (e.g. <!DOCTYPE html>)
Root Element (e.g., <html> )
Head Section
Enclosing <body> and </body> elements
Closing </html> element

The Head Section includes style definitions that display the HTML in a style similar to the ChatGPT app. (How did Chilkat do it? We simply asked ChatGPT to generate CSS that is similar in style to the HTML displayed in the ChatGPT app.)

Note: This example requires Chilkat v11.2.0 or greater.
