HTML5 has significantly transformed web design by introducing a range of new features that enhance both the functionality and the user experience of websites. Key features include semantic elements such as <header>, <footer>, and <article>, which provide a clearer structure to web content. This allows search engines to better understand and index your content, improving SEO results. Additionally, the introduction of multimedia support through tags like <video> and <audio> enables rich media integration without the need for third-party plugins, enhancing site performance and accessibility.

Moreover, HTML5 offers Canvas and SVG elements, empowering developers to create dynamic graphics and animations directly in the browser. These tools revolutionize the way interactive content is delivered, making websites more engaging. With built-in form controls and the Web Storage API, HTML5 also enhances user interaction by allowing for better data management and reduced server load. As a result, these key features not only improve the aesthetics of web pages but also contribute to a more efficient and user-friendly online experience.
