How to add this custom background to the first section of a home page?

Site URL: https://vincentgarreau.com/particles.js/#default

Does anyone know how to add this on the first section of a home page? https://vincentgarreau.com/particles.js/#default

Also, how can I change the color as needed? Looking to use a light grey color instead of the default red.

Copy this into Page header injection

<script src="https://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js"></script><script src="https://threejs.org/examples/js/libs/stats.min.js"></script>      
<style>
  #particles-js{ --particle-background: #ccc;position:absolute; width: 100%; height: 100%; background-color: var(--particle-background); background-image: url(""); background-repeat: no-repeat; background-size: cover; background-position: 50% 50%; } 
</style>
<script>
  document.addEventListener('DOMContentLoaded', function() {
    var firstSection =  document.querySelector(".homepage #page section:first-child .section-background");
    if (firstSection) { firstSection.id = "particles-js" };
    /* Generated code from particle website */
    particlesJS("particles-js", {"particles":{"number":{"value":80,"density":{"enable":true,"value_area":800}},"color":{"value":"#ffffff"},"shape":{"type":"circle","stroke":{"width":0,"color":"#000000"},"polygon":{"nb_sides":5},"image":{"src":"img/github.svg","width":100,"height":100}},"opacity":{"value":0.5,"random":false,"anim":{"enable":false,"speed":1,"opacity_min":0.1,"sync":false}},"size":{"value":3,"random":true,"anim":{"enable":false,"speed":40,"size_min":0.1,"sync":false}},"line_linked":{"enable":true,"distance":150,"color":"#ffffff","opacity":0.4,"width":1},"move":{"enable":true,"speed":6,"direction":"none","random":false,"straight":false,"out_mode":"out","bounce":false,"attract":{"enable":false,"rotateX":600,"rotateY":1200}}},"interactivity":{"detect_on":"canvas","events":{"onhover":{"enable":true,"mode":"repulse"},"onclick":{"enable":true,"mode":"push"},"resize":true},"modes":{"grab":{"distance":400,"line_linked":{"opacity":1}},"bubble":{"distance":400,"size":40,"duration":2,"opacity":8,"speed":3},"repulse":{"distance":200,"duration":0.4},"push":{"particles_nb":4},"remove":{"particles_nb":2}}},"retina_detect":true});
  });
</script>

Find and change the value of css variable particle background as you wish

--particle-background: #ccc;

Hi bangank36, when I copy and paste this into the page header injection, nothing shows up still. Do I add a code block or do anything else? Thanks for your help.
