Hi @rashadb, thanks for paging me 
Are you trying to modify the webflow.js? We do not support nor recommend editing that file, rather try to accomplish your interaction effects using the built in triggers.
Can you please update your post with some more information so we can help you faster? Things like your read-only link, and screenshots of the elements in question really speed things up.
Posting guidelines can be found here: Posting Guidelines for the Design Help Category - General - Forum | Webflow
Thanks in advance!
Cheers,
Dave
