Course Introduction：The parallax scrolling effect can be achieved through CSS, and the core is to make the background and content scrolling speed different. Specific methods: 1. Use background-attachment:fixed to achieve basic parallax; 2. Use a hierarchical structure to control the scrolling speed of each layer through background-position and JavaScript; 3. Pay attention to performance optimization, mobile adaptation and reasonable use of hierarchical effects to improve the experience.

Course Introduction：The key to making parallax scrolling effect is to allow elements of different layers to scroll at different speeds. 1. First, build a multi-layer HTML structure, including background, medium scene and foreground, and use CSS to set the container overflow:hidden and absolute positioning; 2. Then listen to scroll events through JavaScript, use transform:translateY() to dynamically adjust the positions of each layer. The background layer scrolls slowly and the medium scene is slightly faster; 3. Finally, optimize performance, use throttling functions to control the scrolling frequency, compress image resources and adapt to the mobile terminal, and consider pure CSS solutions to improve compatibility.

Course Introduction：To realize the parallax scrolling effect in HTML5, you need to combine HTML, CSS and JavaScript. The core is to allow different page elements to scroll at different speeds. 1. The HTML structure should contain multiple independent layers, such as using different class names to represent background, intermediate content and foreground. 2. CSS uses position:absolute and translateZ to create a 3D depth sense. The smaller the value of the background layer, the slower the scrolling. 3. JavaScript can listen to scroll events, dynamically adjust the translateY value, and control the scroll speed of each layer by multiplying by a coefficient. 4. Pay attention to performance optimization and use requestAnimationFrame
