HTML5 is a markup language used for structuring and presenting content on the World Wide Web. HTML5 introduces elements and attributes that reflect typical usage on modern websites. HTML5 helps you build fast and adaptable web apps or sites.
Browsers supporting HTML5 are
- Latest versions of Apple Safari
- Google Chrome
- Mozilla Firefox
- Opera all support many HTML5 features
- Internet Explorer 9.0 also support for some HTML5 functionality
- Mobile web browsers that come pre-installed on iPhones, iPads, and Android phones have excellent support for HTML5
HTML5 is designed, as much as possible, to be backward compatible with existing web browsers. New features build on existing features and allow you to provide fallback content for older browsers.
