Overview
HTML5 and CSS3 are the latest versions of the core web technologies used to structure and style web content. HTML5 introduces new semantic elements like article tag, section tag, and nav tag to improve the structure of web pages. It also adds new APIs, including support for audio, video, canvas for drawing, and offline storage, making it more powerful for web applications. CSS3 introduces a wide range of features for better styling, including media queries for responsive design, transitions, animations, and flexbox for better layout control.
