if you notice the alt text, that is a transparent image of a leaf i have pathed it and i want to add more of them with different paths, behind them there is a background that you can't see, I am just wondering whether there is a better way to animate about 10 more leaves at different points on the backgrond and if there is a way to make them fall all the way down on the ".animation" selector as at the moment they go about half way

I apologise about the codepen missing images, But i am trying to make a tree that scrolls horizontally and make about a dozen leaves fall with different paths, all while the background moves to a side at the moment i am struggling to make both work properly, if both do end up working the leaf is slower than the background and stays way too far behind or it simply stops at around the middle of the screen and i am trying to make the leaves fall to the ground is there any advise you could give on the issue? Thank you
