Hello! I need help implementing animation into an SVG image I made. Its just a line that I would like to animate as you scroll down the page (the line forming down the page while scrolling)

So far, I've only managed to have the SVG appear but it simply sits on top of all the elements without moving or animating.

Does anyone know a code to have the SVG animate ? I've attached the current code I am working with. I am not too advanced with JavaScript, so animating the svg is proving to be a challenge for me. Any help on this would be greatly appreciated! Thank you!

<style>

body {

height: 500vh;

margin: 0;

z-index:9999999;

}

.line-container {

position:fixed;

top:0;

left:0;

width: 100%;

height: 100%;

text-align: center;

overflow: hidden;

z-index:9999999;

}

svg{

display: inline-block;

height:100%;

z-index:9999999;

}

</style>

let path = document.querySelector('path')

let pathLength = path.getTotalLength()

path.style.strokeDasharray = pathLength + '' + pathLength;

path.style.strokeDashoffset = pathLength;

window.addEventListener('scroll',()=>{

var scrollPercentage = (document.documentElement.scrollTop + document.body.scrollTop) / (document.documentElement.scrollHeight - document.documentElement.clientHeight);

var drawLength = pathLength * scrollPercentage;

path.style.strokeDashoffset = pathLength - drawLength;

}

Hi thank you for your response! I have pasted this and it still does not work. I'm not sure why? I've seen some of your videos on how to incorporate codepen into squarespace and tried doing that but it messes up the entire layout of my site. Not sure if I am doing something wrong.

August 10, 2022

codepen:https://codepen.io/robin-dela/pen/KKPYoBq

I have been trying to add this code into my sight, but I cannot seem to make it work. I have also tried adding it to a new section that uses the new Squarespace fluid engine and it appears to not even work at all versus applying the code to a code block in the previous version. Any help with this would be greatly appreciated!
