How does HTML5 differ from previous versions of HTML?

HTML5 is the latest version of HTML and it differs from previous versions in several ways. Some of the main differences between HTML5 and previous versions of HTML include:

1. Semantic Elements: HTML5 introduces a set of semantic elements that provide more meaning to the content, including <header>, <nav>, <section>, <article>, <aside>, <figure>, and <figcaption>. These elements help to make the structure of the web page more meaningful and improve accessibility for users and search engines.
2. Multimedia Support: HTML5 includes native support for multimedia content, such as video and audio, with the <video> and <audio> elements. This eliminates the need for third-party plugins like Flash.
3. Improved Forms: HTML5 introduces new form elements, including <datalist>, <output>, <progress>, <meter>, and <keygen>, which make it easier to create and validate forms. HTML5 also includes new attributes for form controls, such as the pattern attribute for input validation.
4. Local Storage: HTML5 introduced the concept of local storage, which allows web applications to store data locally on the user’s device, instead of relying on cookies. This provides a faster and more secure way to store data and eliminates the need for server-side storage.
5. Web Sockets: HTML5 introduced a new communication channel called Web Sockets, which allows bidirectional communication between a web browser and a server in real-time. This enables new possibilities for web applications and improves the overall user experience.
6. Deprecated Elements: HTML5 deprecates several elements from previous versions of HTML, such as the <font> element, the <center> element, and the <strike> element. These elements are no longer considered best practice and should be replaced with CSS for styling purposes.
7. Error Handling: HTML5 includes improved error handling, making it easier to detect and correct errors in the code.

These are some of the key differences between HTML5 and previous versions of HTML. HTML5 represents a major evolution in the development of HTML and provides many new features and capabilities that make it easier to create and maintain web content and applications.
