Best Practices for Writing Clean Markdown
Use Consistent Heading Levels:
Follow a logical heading hierarchy without skipping levels. Always add a space after # symbols. See the Markdown heading syntax guide for details.
Use a Markdown Preview:
Modern code editors like VS Code with Markdown Preview Enhanced let you see rendered output as you type, catching errors early.
Always Close Formatting Tags:
Every opening formatting marker must have a matching closing marker. This applies to bold (**), italic (*), and strikethrough (~~) syntax.
Use Blank Lines Between Elements:
Separate headings, paragraphs, lists, and code blocks with blank lines for consistent rendering across parsers. See the CommonMark specification for details.
