Article Introduction：The position attribute has four values: relative, absolute, fixed, and sticky, and their behaviors are different. 1. Relative: The element is offset from its original position and is still in the document flow; 2. Absolute: Depart from the document flow, positioning relative to the nearest positioning ancestor elements; 3. Fixed: Depart from the document flow, always positioning relative to the viewport, keeping the position unchanged when scrolling the page; 4. Sticky: Between relative and fixed, according to the scroll position switching behavior, you need to specify top, bottom and other values ??to take effect, which are often used to fix the header or sidebar.

Article Introduction：Core points Scroll-based animations and special effects are a technology that allows web developers to create dynamic interactive web experiences. They are triggered when the user scrolls down the page and can be manipulated and implemented with CSS and jQuery. To create responsive scroll-based effects, you must define the width and height properties of the browser window. Without these properties, the effects will not work properly when the user resizes the window. This tutorial provides four scroll-based animations and effects examples that demonstrate how they vary based on the value of the window width attribute. These examples include animation of opacity, height, width, left, right, and bottom properties of various elements. This tutorial also contains a FAQ section that provides solutions to FAQ

Article Introduction：CSSScrollSnap improves the scrolling experience through adsorption effects. Common scenarios include horizontal scrolling navigation bar, vertical paginated scrolling and local adsorption in multi-column layouts. For horizontal scrolling, you need to set the container to flex layout and use scroll-snap-align:start; for vertical scrolling, you must unify the page height and combine scroll-snap-type:ymandatory; local adsorption is suitable for card lists, and scroll-snap-align:center is commonly used to achieve centered sliding. Notes include compatibility issues, incomplete support for some browsers, and conflicts with fixed positioning or transform. It is recommended to test different devices and browsers during development.

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：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 z-index attribute controls the display level of positioning elements (such as relative, absolute or fixed positioning) in the page by setting the stacking order of elements. The specific rules are as follows: 1. z-index only takes effect on elements that have non-static positioning; 2. The larger the value, the higher the level, but be careful to avoid the abuse of high numerical values to cause confusion; 3. The elements must be compared in the same stacking context to be effective. The z-index of the parent container will limit the maximum display level of the child elements; 4. Common problems include not setting the position attribute, the parent created an independent stacking context or third-party CSS coverage, which can be solved by checking and adjusting the value layer by layer through the browser developer tools.

Mastering these details can improve the display effect and appear more professional.

Article Introduction：The div element is used in HTML to structure web content and group other elements as containers. It has no visual effect itself, but it can realize layout and design in combination with CSS or JavaScript. Common uses include dividing page areas, combining form elements, and building responsive grid systems. By adding a class or ID, you can control background, spacing, and positioning for it applying styles or scripts. However, divs should not be used excessively, and labels with clearer semantics such as headers, footers, etc. should be given priority to improve accessibility and SEO.
