What's new in HTML 5
The new features:
- <video> and <audio> tags for media playback (say goodbye to Flash players);
- structural tags <article>, <section>, <nav>, <aside>, and <footer> (used instead of <div class="section"> and <div id="footer">; the benefits are improved recognition of the page elements by search engines and screen readers);
- new control types for web forms (email and URL fields, color and date picker, spinbox, slider, progress bar, meter, and key pair generator);
- <menu> tag for creating hierarchical menus, toolbars, and context menus;
- Geolocation API for tracking user's location from GPS or Wi-Fi data (test in your browser; only Firefox works now);
- standardized attributes for drag-and-drop, WYSIWYG editing, and spell checking;
- simplified <!doctype html> and <meta charset="..."> tags.
- Vaullt. HTML 5 <video> showcase. See also page source (<nav>, <aside>, and <footer> are used for structural markup).
- Games using HTML 5 canvas. A Doom-style shooter and a 3D tetris.
- LOGO interpreter in your browser (using <canvas>).
