Can I write raw HTML tags inside a Markdown file?

Yes. The standard Markdown specification fully supports inline HTML. If Markdown doesn't have a native tag for a feature (like subscript, details summary, or custom spacing), you can write standard HTML elements directly inside the document.

Which is better for website SEO, Markdown or HTML?

For search engines, they are equivalent. Markdown is compiled into standard semantic HTML before it is served to web browsers. What Google indexes is the final HTML structure, so both produce the same SEO outcomes as long as appropriate tags (h1, strong, a) are used.

Does Markdown require compilation?

Yes. Browsers cannot parse or render Markdown syntax natively. Before rendering on a web page, the markdown code must pass through a parser/compiler (like our custom parser, marked, or mdX) to translate it into standard HTML DOM elements.

Core Concepts

While **HTML** is the underlying native standard of the World Wide Web, **Markdown** was created as a lightweight plain-text formatting syntax that developers can easily read and write, which compiles cleanly into HTML.

Markdown Syntax Shorthand

# Title
This is **bold** text and [a link](https://example.com).

Compiled HTML Document

<h1>Title</h1>
<p>This is <strong>bold</strong> text and <a href="https://example.com">a link</a>.</p>

Detailed Comparison Table

Feature	Markdown	HTML
Readability	High (looks like clean plain-text)	Low (obstructed by opening/closing tag structures)
Browser Support	Requires compile parser to render	Natively supported by 100% of browsers
Syntax Complexity	Extremely simple (minimal symbols like #, *)	Verbose (requires brackets, tags, attributes)
XSS Security	High (most parsers escape raw HTML strings)	Requires manual sanitization of injection vulnerabilities
Custom Styling	Limited (relies on style stylesheets)	Unlimited (supports inline styles, classes, id tags)

Which Format Should You Choose?

- **Choose Markdown** if you are writing developer READMEs, repository documentation, user guides, or writing blog content where raw typing speed and readability are paramount. - **Choose HTML** if you are building complex page layouts, embedding interactive layouts, designing custom emails, or require custom CSS styling overrides directly in the code structure.
