JS를 이용하여 진행. 카드와 눈의 움직임을 부여

eye.style.transform = `translate(${-x}px, ${-y}px)`;
wrap.style.transform = `translate(-50%, -50%) perspective(600px) rotateX(${-y}deg) rotateY(${-x}deg)`
requestAnimationFrame(animate);
}

window.addEventListener('mousemove', (e)=>{
let mouseX = Math.max(-100, Math.min(100, window.innerWidth / 2 - e.clientX));
let mouseY = Math.max(-100, Math.min(100, window.innerHeight / 2 - e.clientY));

followX = (12 * mouseX) / 100;
followY = (10 * mouseY) / 100;
});

window.addEventListener('keydown', (e) => {
switch(e.keyCode){
    case 37:
        followX = 12;
