HTML5 is the latest version of the Hypertext Markup Language, which is the standard language used to create and design web pages. It provides a structure for web content, allowing developers to organize text, images, and multimedia elements effectively. With HTML5, websites can be more interactive and visually appealing, thanks to new features like audio and video support without needing additional plugins. One of the key benefits of HTML5 is its ability to work seamlessly across different devices, such as smartphones, tablets, and computers. This means that users can enjoy a consistent experience, whether they are browsing on a desktop or a mobile device. Additionally, HTML5 supports advanced features like geolocation and local storage, enhancing the functionality of web applications.
