CSS 'position: sticky' - Introduction and Polyfills
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

how to change page size in Word
Article Introduction：To resolve Word page size modification issues, first find the Size option in the Layout or Page Layout tab, select a standard size, or set the width and height via Custom Size. If the document does not change after the page size changes, it may be due to section breaks, fixed margins, or text box restrictions. You should check the section breaks and adjust them section by section, or modify the text box manually. If the page does not match during printing, you need to check whether the printer driver settings are consistent with the document and confirm whether the default settings of the template affect the output effect.

How to make a parallax scrolling effect with HTML5?
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
