HTML defines the structure of every web page — headings, paragraphs, links, forms — using tags that browsers interpret to decide what to render and how. It's the one format every browser on every platform is guaranteed to understand, since it's the foundation the web itself is built on.

On its own, HTML only handles structure and semantics; visual styling comes from CSS and interactivity from JavaScript, both of which typically live alongside or embedded within an HTML document.

The sample below is useful for testing an HTML parser, a sanitization library, or a rendering pipeline against real markup rather than a hand-written string that might not reflect how actual web pages are structured.
