Frequently Asked Questions
What Markdown flavors are supported?
We support CommonMark with GitHub Flavored Markdown extensions, including tables, task lists, strikethrough, and autolinks.
Is syntax highlighting supported?
Yes! Specify the language after code fence backticks:
```javascript
const hello = "world";
### How do I handle special characters?
Escape special Markdown characters with backslash: `\*not italic\*`
### Can I include raw HTML in Markdown?
Yes! Markdown allows inline HTML: `<strong>custom HTML</strong>`
### Does the converter sanitize HTML?
Basic sanitization removes potentially harmful scripts. For user-generated content, implement server-side sanitization.
### What about math equations?
MathJax or KaTeX syntax is preserved. Add the appropriate JavaScript library to render equations.

## Pro Tips
1. **Use reference links** — Keep Markdown readable with links at bottom
2. **Two spaces for line break** — Force line breaks without new paragraph
3. **Escape when needed** — Use `\` before special characters
4. **Preview before publishing** — Always check rendered output
5. **Use extensions wisely** — Not all renderers support all features
