Issue
I am creating my portfolio page which I am currently animating the buttons' animation and my background is a simple particle animation as my background which powered by javascript. I noticed that the canvas which is the simple particle animation in the css file which I have set my canvas position to other elements except for absolute which is preventing the buttons animation from animating.
I tried changing the position to other elements and it's works for the buttons animation but when I changed the canvas position to absolute , the buttons' animation stopped working again
Here's my code ( html code )
<!DOCTYPE html>

javascript file
const canvas = document.getElementById('waveCanvas');
const ctx = canvas.getContext('2d');
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
let particlesArray;
// Define particle properties
class Particle {

if (this.size > 0.2) this.size -= 0.1;
}
draw() {
ctx.fillStyle = 'white';
ctx.beginPath();
ctx.arc(this.x, this.y, this.size, 0, Math.PI * 2);
ctx.closePath();
ctx.fill();
}
}
function init() {
particlesArray = [];
for (let i = 0; i < 1000; i++) {
particlesArray.push(new Particle());
}
}
function animate() {
requestAnimationFrame(animate);
ctx.clearRect(0, 0, canvas.width, canvas.height);
for (let i = 0; i < particlesArray.length; i++) {
particlesArray[i].update();
particlesArray[i].draw();
// Reset particles when they go off-screen
if (particlesArray[i].x < 0 || particlesArray[i].x > canvas.width || particlesArray[i].y < 0 || particlesArray[i].y > canvas.height) {
particlesArray[i] = new Particle();
}
}
}
init();
animate();
// Update canvas size when the window is resized
window.addEventListener('resize', () => {
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
init();
});
Solution
The canvas being on top of everything, prevents the buttons from being hovered with the cursor.
Just add pointer-events: none; for your canvas element, so that it "ignores" the mouse cursor.
