Wtf does this do

This GitHub repository, called css-parallax, provides a simple parallax scrolling effect built entirely with HTML and CSS. Parallax is the visual technique where background elements on a webpage move at a different speed than the foreground content as you scroll down, creating an illusion of depth. Web developers often use this to make landing pages feel more dynamic, immersive, and engaging for visitors. The project demonstrates how to achieve this depth effect without relying on JavaScript. While the repository does not include a detailed written guide, the code itself shows how to layer images and text using standard web styling rules. By adjusting how background images are positioned and attached relative to the rest of the page, the creator shows how the viewer's scrolling motion naturally shifts the visual layers at different speeds. This creates the classic parallax illusion entirely within the browser's native styling capabilities. This resource is ideal for beginner web developers, design-conscious founders, or product managers who want to understand and implement a popular visual effect without adding extra complexity to their site. For example, if a founder is building a portfolio site or a product landing page and wants a visually striking hero section that stands out to users, this code provides a ready-made template to study and adapt. It offers a straightforward way to see exactly how the effect is structured so it can be copied and customized. The most notable aspect of this project is its strict reliance on pure CSS. Many parallax implementations require JavaScript to calculate scroll positions and move elements on the fly, which can add to page load times and complexity. By solving the problem with standard styling rules alone, this approach keeps the implementation lightweight and easy to maintain, making it an excellent learning tool for anyone looking to add a touch of visual polish to a website without introducing unnecessary technical overhead.
