Markdown rendering can fail due to several common issues:

• Missing blank lines between paragraphs and lists
• Incorrect indentation (use 2 or 4 spaces consistently)
• Special characters not escaped with backslash (\)
• Mixing HTML and Markdown incorrectly
• Platform-specific Markdown flavors (GitHub, CommonMark)

Create beautiful code blocks with syntax highlighting using triple backticks and language identifiers:

• Use ```javascript for JavaScript highlighting
• Support for 100+ languages (python, java, rust, etc.)
• Add line numbers with some Markdown processors
• Inline code with single backticks `code`
• Code block titles and file names in some flavors

Markdown can pose security risks if not properly sanitized:

• Raw HTML in Markdown can contain malicious scripts
• Always sanitize user-generated Markdown content
• Use trusted Markdown parsers with built-in security
• Disable HTML rendering for untrusted content
• Validate and escape special characters properly

Modern Markdown supports many advanced features beyond basic formatting:

• Tables with alignment and formatting
• Task lists with checkboxes [ ] and [x]
• Footnotes and references for academic writing
• Mermaid diagrams for flowcharts and graphs
• Mathematical expressions with LaTeX syntax

Markdown preview can be styled to match your needs:

• GitHub-flavored Markdown (GFM) for repositories
• Custom CSS for branded documentation
• Dark mode support for better readability
• Print-friendly styles for PDF generation
• Mobile-responsive preview layouts

Effective team collaboration with Markdown requires good practices:

• Use consistent style guides (Markdownlint)
• Version control with Git for tracking changes
• Automated formatting with Prettier
• Pull request reviews for documentation
• CI/CD integration for docs deployment

Markdown content can be optimized for better search visibility:

• Use proper heading hierarchy (H1 → H2 → H3)
• Include descriptive alt text for images
• Create meaningful link text (avoid "click here")
• Add meta descriptions in frontmatter
• Structure content with semantic HTML output

Different Markdown flavors suit different needs:

• CommonMark: Standard, portable specification
• GitHub Flavored (GFM): Tables, task lists, strikethrough
• MultiMarkdown: Footnotes, citations, metadata
• Markdown Extra: Definition lists, abbreviations
• Pandoc: Academic writing with citations
