Scroll jacking is a web design technique where a website takes control of the user's scrolling behavior. Instead of allowing users to scroll normally, the site may create a custom scrolling experience that can include animations or transitions. This can lead to a more engaging experience but may also frustrate users who prefer standard scrolling. While scroll jacking can enhance visual storytelling, it can also hinder usability. Users might find it difficult to navigate or may feel disoriented if the scrolling does not behave as expected. Designers must balance creativity with user experience to avoid negative impacts on site engagement.
