How i Created This Design
Scroll Event Listener: This JavaScript code adds an event listener to the window, which listens for scroll events as the user scrolls down the webpage.
Image Selection: It selects an image element within the HTML document by its ID, 'fixed-image,' and then further queries for an <img> element within it.
Scroll Position: The code captures the current vertical scroll position of the webpage, which represents how far the user has scrolled down the page.
Image Filenames: It defines an array called imageFilenames that should contain a list of image filenames. Each filename corresponds to a different scroll position on the page. These filenames determine which image is displayed based on how far the user has scrolled.
Threshold: A threshold value is defined, which determines the scrolling distance required to trigger a change in the displayed image. In your code, it's set to 19.
Image Index Calculation: The code calculates an imageIndex based on the scroll position and the threshold. This index corresponds to the position in the imageFilenames array, indicating which image should be displayed.
Index Limitation: The code ensures that the imageIndex does not go beyond the available images in the imageFilenames array.
Image Source Update: Finally, the code updates the src attribute of the selected <img> element with the filename determined by the imageIndex. As a result, the displayed image changes as the user scrolls down the webpage.
