Never-Ending Webpage After Cursor Animation Code

Hi Everyone,

I am designing a squarespace website and am attempting to add in a cursor animation with the code injection feature. The code works great for the cursor animation, however, when I use the code, the website trails off after the footer and becomes a never-ending scrolling of a blank page following the footer. I've tried going in and tweaking the code but am no coder so haven't been able to figure it out. 

I was hoping someone here with a coding background may be able to help resolve this issue. Please find the code I am using below:

<script>

var colour="random"; // "random" can be replaced with any valid colour ie: "red"...

var sparkles=100;// increase of decrease for number of sparkles falling
