Frequently Asked Questions

Is Markdown better than HTML?

Markdown is better for writing content quickly and readably, while HTML offers more control and flexibility. For most content creation, Markdown is faster and easier. Use HTML when you need precise control over layout and styling.

Can I use HTML inside Markdown?

Yes! Most Markdown processors allow you to include raw HTML for features not supported by Markdown syntax. This gives you the best of both worlds - simple Markdown for most content, HTML for complex elements.

What's the difference between .md and .markdown files?

There's no functional difference - both are Markdown files. .md is more common due to being shorter. Use whichever your project or team prefers, but be consistent.

How do I add custom CSS to Markdown?

Markdown itself doesn't support CSS. After converting to HTML, you can add CSS styling. Some Markdown processors allow inline HTML with style attributes, or you can link external CSS files in your HTML output.

Is Markdown secure?

Markdown itself is safe, but be cautious when allowing user-submitted Markdown that converts to HTML. Always sanitize HTML output to prevent XSS attacks. Most modern Markdown processors include security features.

Can I convert HTML back to Markdown?

Yes, there are HTML-to-Markdown converters available. However, complex HTML with custom styling may not convert perfectly, as Markdown has limited formatting options compared to HTML.
