Issues with a website

I am trying to copy an entire site, my own: https://holisticleaders.co/
I want to move it to another system, but it does not copy some styles..

Here is the result in the other system (same result as locally):

1. Main question: How can I get it to copy everything so it looks identical?

2. Also another question, is it possible to copy over js functionality with the tool?
