The working principle of H5 depends on the collaborative work of HTML5, CSS3 and JavaScript. HTML5 provides structure and semantics, CSS3 is responsible for style and layout, and JavaScript is responsible for interactive and dynamic content. Together, they form a powerful technology stack that enables developers to create a rich and diverse web application.<\/p>
In terms of implementation principle, the core of the H5 technology stack is to use the browser's rendering engine and JavaScript engine to process and display web page content.
