Hi @Yaser Arafat. We love helping with GSAP-related questions, but unfortunately we just don't have the resources to provide free general consulting, logic troubleshooting, or "here's my live site...please tell me why it is broken" requests. Of course anyone else is welcome to post an answer if they'd like - we just want to manage expectations.  

 

You can post in the "Jobs & Freelance" forum for paid consulting, or contact us directly. 

 

Otherwise, if you've got a GSAP-specific question just post that here along with a minimal demo and we'd be happy to take a look.
