HTML5 is a standard for building and presenting web content that introduces many new features and capabilities to provide a better user experience and richer web applications. The following are some of the main new features of HTML5:

Semantic tags: HTML5 introduces some new semantic tags, such as

,

,

,

,

and

, used to better describe and organize web page content, so that search engines and browsers can better understand and process the page structure.

Video and audio: HTML5 provides the

Canvas: HTML5's tag allows the use of JavaScript to draw graphics, animations and images on web pages. This provides a native way to create interactive and dynamic graphics such as games and data visualizations.

Geolocation: HTML5 provides a standard way to obtain the user's location in a web application through the navigator.geolocation API. This allows developers to create location-based applications such as map navigation, nearby stores, and social media.

Storage: HTML5 introduces two new client-side storage mechanisms, namely localStorage and sessionStorage. These mechanisms allow data to be stored in the browser so that it can be shared and retained across different pages and sessions. This provides better support for offline use and local caching.

Web Workers: Web Workers for HTML5 allow running scripts in the background without blocking the user interface. This makes it possible to create multi-threaded web applications, improving performance and responsiveness.

Drag and drop: HTML5’s drag and drop API makes it easier to implement drag and drop operations in web pages. Developers can use new events and methods to drag and drop from one element to another, allowing for more intuitive and interactive user interfaces.

Web Storage: HTML5 introduces a new web storage API, IndexedDB, which provides a way to store structured data in the browser. Developers can use this API to create complex database applications such as instant messaging and offline reading.

Web Components: Web Components of HTML5 is a technology for creating reusable and independent web components. It consists of three main technologies: custom elements, shadow DOM and HTML templates. This allows developers to create custom HTML elements and encapsulate them as independent components for reuse in different projects and frameworks.

Responsive Design: HTML5 makes it easier to develop responsive web designs. It provides some new CSS features such as media queries and elastic layout to adjust and optimize web page layout and style according to different devices and screen sizes.

These are just some of the major new features of HTML5, which also includes many other features and APIs, such as form enhancements, animations, network sockets, and real-time communication. The introduction of HTML5 provides web developers with more tools and capabilities to create richer, interactive and dynamic web applications.
