So I have created a landing page for a client's website. They apparenlty can't upload the folder with the JS files, so they need all the JS and CSS in one same file.

I started putting (before the body section) all the CSS putting it into and the JS putting in into , but all the animations inside the JS don't work.

Is there any way/advice on how to put it all together?

Thanks!

Ps: I could give more info if needed!
