I got the particle to move around which is what I wanted, but I want to add a little trail that will fade a way and I am not sure how to go about doing that
Is it possible to do with only css? or do I have to involve jquery in this?
Here is a demo: LINK
#object{
position: absolute;
bottom:-2em;
left:0;
right:0;
margin:0 auto;
width: 10px;
height: 10px;
background: red;
-webkit-animation: myOrbit 6s linear infinite;
-moz-animation: myOrbit 6s linear infinite;
-o-animation: myOrbit 6s linear infinite;
animation: myOrbit 6s linear infinite;
}
@-webkit-keyframes myOrbit {
0% { -webkit-transform: rotate(0deg) translateX(5px) translateY(400px) rotate(0deg) scale(1); }
25% { -webkit-transform: rotate(90deg) translateX(5px) translateY(400px) rotate(-90deg) scale(.60); }
50% { -webkit-transform: rotate(180deg) translateX(5px) translateY(400px) rotate(-180deg) scale(.30); }
75% { -webkit-transform: rotate(270deg) translateX(5px) translateY(400px) rotate(-270deg) scale(.60); }
100% { -webkit-transform: rotate(360deg) translateX(5px) translateY(400px) rotate(-360deg) scale(1); }
}
@-moz-keyframes myOrbit {
0% { -moz-transform: rotate(0deg) translateX(5px) translateY(400px) rotate(0deg) scale(1); }
25% { -moz-transform: rotate(90deg) translateX(5px) translateY(400px) rotate(-90deg) scale(.60); }
50% { -moz-transform: rotate(180deg) translateX(5px) translateY(400px) rotate(-180deg) scale(.30); }
75% { -moz-transform: rotate(270deg) translateX(5px) translateY(400px) rotate(-270deg) scale(.60); }
100% { -moz-transform: rotate(360deg) translateX(5px) translateY(400px) rotate(-360deg) scale(1); }
}
@-o-keyframes myOrbit {
0% { -o-transform: rotate(0deg) translateX(5px) translateY(400px) rotate(0deg) scale(1); }
25% { -o-transform: rotate(90deg) translateX(5px) translateY(400px) rotate(-90deg) scale(.60); }
50% { -o-transform: rotate(180deg) translateX(5px) translateY(400px) rotate(-180deg) scale(.30); }

}

0% { transform: rotate(0deg) translateX(5px) translateY(400px) rotate(0deg) scale(1); }
25% { transform: rotate(90deg) translateX(5px) translateY(400px) rotate(-90deg) scale(.60); }
50% { transform: rotate(180deg) translateX(5px) translateY(400px) rotate(-180deg) scale(.30); }

I was doing something similar which is how I found this question. I took what I came up with and adapted it to your answer. Not sure it will work for what you're doing but it's still fun.
http://jsfiddle.net/y40kwyhr/2/
var obj = document.getElementById("object");
class Particle {
constructor(parent) {
this.div = document.createElement("div");
this.div.classList.add("particle");
this.div.classList.add("twinkle");
this.div.id = "particle-" + Date.now();
parent.appendChild(this.div);
setTimeout(() => { // remove particle
if(this.driftIntervalId) clearInterval(this.driftIntervalId);
this.div.remove();
}, 400);
}
drift(speed = 1) {
var rad = Math.PI * Math.random();
this.driftIntervalId = setInterval(() => {
var left = +this.div.style.left.replace("px",'');
var top = +this.div.style.top.replace("px",'');
left += Math.sin(rad) * speed;
top += Math.cos(rad) * speed;
this.div.style.left = left + "px";
this.div.style.top = top + "px";
}, 10);
}
}
var particleFactory = function(meteor) {
var rect = meteor.getBoundingClientRect();
var particle = new Particle(meteor.parentElement);
particle.div.style.left = rect.left + "px";
particle.div.style.top = rect.top + "px";
particle.drift(0.4);
setTimeout(() => {
particleFactory(meteor);
}, 100);
};
particleFactory(obj);
