The site looks very cool but there are so many effects, I don’t know which one you mean. ^^
What I see so far is that for most of the effects you will need some custom code. And I think that especially if you are new in the world of webdesign/webflow those effects will take you quite a while to get them to work.
I think even for pros this site took much more time than a “standard” website without animations. Thats just something I think you should consider doing your new website.
