Answer 1

To get you started:
Spelling:
infinite, lines 19-20
height, line 25

Suggestion, either or both:
Use different colors for each panel (not all grey):
background-color:green; /* red, blue, etc */

Add content to each div:
<div id="side1">1</div>

This should let you see a partial animation, which should help you debug it (then, someone else may help here; I'm currently distracted).

Answer 2

add this script so you don't have to worry about prefixes:

<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>

It will make your code clearer.

Answer 3

I didn't get the output😭😭😭 still
