HTML5 is the modern HTML specification that moved the web from static pages toward richer, app-like experiences. Beyond a shorter doctype and cleaner syntax, it introduced semantic structural tags, new form controls, client-side storage and networking APIs, drawing and multimedia capabilities, and better hooks for accessibility — all intended to make markup clearer for browsers, developers and assistive tech.

Key practical points:

  • Structural/semantic elements: header, nav, main, article, section, aside, footer, figure/figcaption — use these for clearer page structure and better accessibility.
  • Forms: new input types and attributes (email, number, date, placeholder, required, pattern) reduce JS work and improve validation.
  • Graphics & media: canvas and SVG for drawing; native media playback without plugins (keep fallback strategies).
  • Storage & networking: localStorage/sessionStorage, fetch/WebSocket, and service workers (preferred for offline/caching; AppCache is obsolete).
  • Accessibility: prefer native semantics first, add ARIA only where needed.
  • Compatibility: support varies by feature; use feature detection, polyfills/shims, and progressive enhancement rather than user-agent sniffing.

Minimal HTML5 starter (use as a cheat-sheet):

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width,initial-scale=1">
  <title>Minimal HTML5</title>
</head>
<body>
  <header>Site heading</header>
  <main>Content</main>
  <footer>Footer</footer>
</body>
</html>

Notes and troubleshooting: as pointed out, a simple page may look the same at first glance, but the new elements and APIs matter for structure, accessibility and interactivity. For older browsers that don't recognize new tags, use a small shim or createElement technique and set unknown elements to display:block in CSS. Feature-detect (e.g., Modernizr) and test on target devices; rely on progressive enhancement so features degrade gracefully. References in this thread (official spec pointers and compatibility tables) are useful starting places for specifics.

Dear Carmen, I think most of use here are wondering why you're asking such a question. A simple google search will give you many useful links as to what it is. If you have a question about a specific aspect of HTML5, sure, fire away - but what is HTML5 is like asking what's an elephant. Sorry if you find this patronizing, it's not meant to be.

I'll be brief with my own half-cocked explo:

HTML5 decades, it seems, in the making, comes of the heels of HMTL4.x and XHTML. It's a markup language subset of SGML. To all intents and purposes, you wouldn't really tell the difference between HTML4 and HTML5 from looking at a basic page other than the DocType Declaration. However, HTML5 comes with a plethora of additional attributes/properties and a few new tags. It also lends itself to working with js moreso that the other doctypes. There's hell of a lot more to it, but those are the bare bones as I see them.

Some attribute/properties are not supported by all browsers and older browsers may not support any of them. This shows a compatibility table for html5: http://caniuse.com/#cats=HTML5

Amol555, I'll just assume that first 'HTML' in your post was supposed to read HTML5?
