I want to design a landing website using HTML and CSS. How do I achieve the scrolling effect when a user scrolling the website and wants to move an animated object through the website? I followed the GSAP and tried to do some scroll trigger animation. This is what I tried:-https://codepen.io/sidath-sansu/pen/jORJ
I wanted to move a PNG image or a 3D animated object from the sketchfab website. I want to design a website like the below image. I found some real websites that used scroll trigger animations to decorate their website. Examples:- bubblidigital, takeboost

I want to move the airplane when scrolling with the dash line path and hide in the last section airplane come and start again at the end of that section. Need to design any kind of cloud movement on the web page while scrolling. Please Help to achieve this design. Please give a source to refer to this kind of design. Please give me the step by step to achieve this with GSAP.
