HTML5 is the fifth and latest major version of the HyperText Markup Language (HTML) standard, used for structuring and presenting content on the web. It introduced new elements, attributes, and APIs to enhance web development and support modern web applications.

Importance of HTML5

HTML5 is important because it:

  • Supports Multimedia: Provides native support for audio and video elements, eliminating the need for third-party plugins.
  • Enhances Semantics: Introduces new semantic elements, such as <article>, <section>, <header>, and <footer>, improving the structure and accessibility of web content.
  • Enables Offline Applications: Includes APIs like Web Storage and Application Cache, allowing web applications to function offline.
  • Improves Performance: Optimizes web page loading and performance with features like lazy loading and the <picture> element for responsive images.

Key Features of HTML5

  • New Elements: Includes new structural and semantic elements, such as <article>, <section>, <nav>, <aside>, <figure>, and <figcaption>.
  • Multimedia Support: Adds native support for audio (<audio>) and video (<video>) elements.
  • APIs and Interfaces: Introduces APIs like Canvas, WebGL, Web Storage, Geolocation, and Web Workers.
  • Form Enhancements: Provides new input types (email, tel, url, date, range, etc.) and form validation attributes.
