Parallax Scrolling Demo

the "Parallax Scrolling Demo - JavaScript" Canvas is designed to explain and optionally implement more advanced parallax scrolling effects. Here's what this specific code snippet does and why it's useful: Core Parallax Explanation: It clarifies that for a basic parallax effect, the CSS property background-attachment: fixed is often sufficient. This means the background image stays in place while the foreground content scrolls over it, creating the illusion of depth. Placeholder for Advanced Effects: While the basic effect relies on CSS, this JavaScript file serves as a placeholder. It indicates where you would add more complex or dynamic parallax behaviors if needed. Commented-Out Example: It includes a commented-out example of how you could implement a more advanced parallax effect using JavaScript. This example demonstrates: Listening for the scroll event on the document. Iterating through elements with the class parallax-section. Calculating a new backgroundPositionY based on the scroll position and a speed factor. Important Note: The comments within the code explain that if you were to use this JavaScript approach for parallax, you would typically remove background-attachment: fixed from your CSS, as the JavaScript would then be directly controlling the background's position.
