Sorry, @Da Gu Gu Gu but we can't really troubleshoot live web sites. There are way too many factors involved. Please read the forum guidelines. If you need some help, please try to reproduce the issue in a minimal demo, like on CodePen or CodeSandbox and we'd be happy to answer any GSAP-specific questions you might have. Or if you'd like to explore paid consulting services, you're welcome to either reach out to us privately or post in the "Jobs & Freelance" forum.
