How to add js/css style to svelte-kit project

Question

I have a js effect called color changin in codepen and i dont how implement it into my svelte-kit project like I tried to implementing this directly into app.css and app.html but it didn't work I dont how to implement it into svelte-kit project and there is my project structure. and here is the codes of effect

canvas {
  display: block;
  width: 100vw;
  height: 100vh;
}

var c = document.getElementById("c");
var ctx = c.getContext("2d");
var cH;
var cW;
var bgColor = "#FF6138";
var animations = [];
var circles = [];

var colorPicker = (function() {
  var colors = ["#FF6138", "#FFBE53", "#2980B9", "#282741"];
  var index = 0;
  function next() {
    index = index++ < colors.length-1 ? index : 0;
    return colors[index];
  }
  function current() {
    return colors[index]
  }
  return {
    next: next,
    current: current
  }
})();

function removeAnimation(animation) {
  var index = animations.indexOf(animation);
  if (index > -1) animations.splice(index, 1);
}

function calcPageFillRadius(x, y) {
  var l = Math.max(x - 0, cW - x);
  var h = Math.max(y - 0, cH - y);
  return Math.sqrt(Math.pow(l, 2) + Math.pow(h, 2));
}

function addClickListeners() {
  document.addEventListener("touchstart", handleEvent);
  document.addEventListener("mousedown", handleEvent);
};

function handleEvent(e) {
    if (e.touches) { 
      e.preventDefault();
      e = e.touches[0];
    }
    var currentColor = colorPicker.current();
    var nextColor = colorPicker.next();
    var targetR = calcPageFillRadius(e.pageX, e.pageY);
    var rippleSize = Math.min(200, (cW * .4));
    var minCoverDuration = 750;
    
    var pageFill = new Circle({
      x: e.pageX,
      y: e.pageY,
      r: 0,
      fill: nextColor
    });
    var fillAnimation = anime({
      targets: pageFill,
      r: targetR,
      duration:  Math.max(targetR / 2 , minCoverDuration ),
      easing: "easeOutQuart",
      complete: function(){
        bgColor = pageFill.fill;
        removeAnimation(fillAnimation);
      }
    });

      r: 0,
      fill: currentColor,
      stroke: {
        width: 3,
        color: currentColor
      },
      opacity: 1
    });
    var rippleAnimation = anime({
      targets: ripple,
      r: rippleSize,
      opacity: 0,
      easing: "easeOutExpo",
      duration: 900,
      complete: removeAnimation
    });
    
    var particles = [];
    for (var i=0; i<32; i++) {
      var particle = new Circle({
        x: e.pageX,
        y: e.pageY,
        fill: currentColor,
        r: anime.random(24, 48)
      })
      particles.push(particle);
    }
    var particlesAnimation = anime({
      targets: particles,
      x: function(particle){
        return particle.x + anime.random(rippleSize, -rippleSize);
      },
      y: function(particle){
        return particle.y + anime.random(rippleSize * 1.15, -rippleSize * 1.15);
      },
      r: 0,
      easing: "easeOutExpo",
      duration: anime.random(1000,1300),
      complete: removeAnimation
    });
    animations.push(fillAnimation, rippleAnimation, particlesAnimation);
}

function extend(a, b){
  for(var key in b) {
    if(b.hasOwnProperty(key)) {
      a[key] = b[key];
    }
  }
  return a;
}

var Circle = function(opts) {
  extend(this, opts);
}

Circle.prototype.draw = function() {
  ctx.globalAlpha = this.opacity || 1;
  ctx.beginPath();
  ctx.arc(this.x, this.y, this.r, 0, 2 * Math.PI, false);

  }

  ctx.closePath();
  ctx.globalAlpha = 1;
}

var animate = anime({
  duration: Infinity,
  update: function() {
    ctx.fillStyle = bgColor;
    ctx.fillRect(0, 0, cW, cH);
    animations.forEach(function(anim) {
      anim.animatables.forEach(function(animatable) {
        animatable.target.draw();
      });
    });
  }
});

var resizeCanvas = function() {
  cW = window.innerWidth;
  cH = window.innerHeight;
  c.width = cW * devicePixelRatio;
  c.height = cH * devicePixelRatio;
  ctx.scale(devicePixelRatio, devicePixelRatio);
};

(function init() {
  resizeCanvas();
  if (window.CP) {
    // CodePen's loop detection was causin' problems
    // and I have no idea why, so...
    window.CP.PenTimer.MAX_TIME_IN_LOOP_WO_EXIT = 6000; 
  }
  window.addEventListener("resize", resizeCanvas);
  addClickListeners();
  if (!!window.location.pathname.match(/fullcpgrid/)) {
    startFauxClicking();
  }
  handleInactiveUser();
})();

function handleInactiveUser() {
  var inactive = setTimeout(function(){
    fauxClick(cW/2, cH/2);
  }, 2000);
  
  function clearInactiveTimeout() {
    clearTimeout(inactive);
    document.removeEventListener("mousedown", clearInactiveTimeout);
    document.removeEventListener("touchstart", clearInactiveTimeout);
  }
  
  document.addEventListener("mousedown", clearInactiveTimeout);
  document.addEventListener("touchstart", clearInactiveTimeout);
}

function startFauxClicking() {
  setTimeout(function(){
    fauxClick(anime.random( cW * .2, cW * .8), anime.random(cH * .2, cH * .8));
    startFauxClicking();
  }, anime.random(200, 900));
}

function fauxClick(x, y) {
  var fauxClick = new Event("mousedown");
  fauxClick.pageX = x;
  fauxClick.pageY = y;
  document.dispatchEvent(fauxClick);
}

implementing that effect into my project properly
