  1. Thank you for providing a detailed response! It's a perfect answer! I appreciate it!
  2. Thank you for your response, mvaneijgen. Actually, I had already tried using the once property, but it didn't work as expected. I created a CodePen to demonstrate the issue. Here's what I found: 1. While the animation progresses as the user scrolls down, it reverses when scrolling up. 2. After all the animations complete, scrolling back up leads to a blank space. Is there something wrong with my code that could be causing these issues? Code Pen https://codepen.io/wevolution-void/pen/vYbwybj

The behavior I aim for, especially for the title animation, includes the following points: - The animation should complete when scrolled through 3000px. - The animation should synchronize with the mouse scroll. - I don't want the animation to reverse when scrolling upwards. - Once 3000px scrolling is completed and the animation ends, I do not want the animation to replay. I am using the scrub feature to sync with mouse scrolling, but I haven't found a parameter that disables reverse playback on upward scrolling. Is there any effective solution for this? I plan to post this on a community forum, so please ensure the translation is suitable for that context. Thank you.
