Frequently Asked Questions
- What is Markdown? — Markdown is a lightweight markup language for creating formatted text using a plain-text editor. It was created by John Gruber in 2004 and is now widely used for documentation, README files, and content management.
- What is GFM? — GitHub Flavored Markdown (GFM) extends standard Markdown with features like tables, task lists, strikethrough, and fenced code blocks. This editor supports all GFM features.
- Is my content saved? — No. All content exists only in your browser's memory. If you refresh the page, your content will be lost. Use "Copy HTML" to save your work.
- Is the output sanitized? — Yes. The preview uses DOMPurify to prevent XSS attacks. Any potentially dangerous HTML is automatically removed.
- Can I use this for writing documentation? — Absolutely. This editor is perfect for writing README files, documentation, blog posts, and any content that uses Markdown formatting.
