Article 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

Article Introduction：The parallax scrolling effect can be implemented using CSS. There are three specific methods: First, use the background-attachment attribute, set the background-attachment:fixed; make the background image fixed, forming visual misalignment; second, use transform:translateZ() and perspective to set multiple levels in HTML and give different depths to simulate the 3D scrolling effect; third, combine HTML, CSS and JavaScript, dynamically adjust the style by listening to scroll events to achieve more complex animation effects. These three methods are applicable to basic parallax, full-screen display websites and high-definition

Article Introduction：Pure CSS can achieve parallax scrolling effect, mainly through background-attachment:fixed and hierarchical structure. 1. Use the background-attachment:fixed attribute to make the background image fixed, and use the background-size and background-position to realize a full-screen background, forming a visual illusion that the background is still when scrolling. 2. Create multiple blocks with different backgrounds through layered layout. Each block applies the same fixed background attribute, so that they are rendered in turn when scrolling, sandwiched between ordinary content to form multiple layers of parallax. 3. Pay attention to mobile compatibility issues, and browsers such as iOSSafari may

Article 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.

Article Introduction：Key Points The position: sticky property of CSS allows the navigation bar or other elements to remain visible when the user scrolls without having to pin it on the page. This property acts like a static position within its parent element until the given offset threshold is reached, at which point it is like the value is set to fixed. Traditionally, the method to achieve this effect involves JavaScript, where scrolling events of a page are listened to and using JavaScript to change the values ??of the position and top attributes based on the current position of the viewport. However, when the position of the element is changed to fixed , this method can cause problems, causing it to leave the page stream and the element below "upward
