The effect is as follows :

Simple and crude code :
<script> !function (e, t, a) { function r() { for (var e = 0; e < s.length; e++
) s[e].alpha <= 0 ? (t.body.removeChild(s[e].el), s.splice(e, 1)) : (s[e].y--, s
[e].scale += .004, s[e].alpha -= .013, s[e].el.style.cssText = "left:" + s[e].x
+ "px;top:" + s[e].y + "px;opacity:" + s[e].alpha + ";transform:scale(" + s[e].
scale+ "," + s[e].scale + ") rotate(45deg);background:" + s[e].color +
";z-index:99999"); requestAnimationFrame(r) } function n() { var t = "function"
== typeof e.onclick && e.onclick; e.onclick = function (e) { t && t(), o(e) } }
function o(e) { var a = t.createElement("div"); a.className = "heart", s.push({
el: a, x: e.clientX - 5, y: e.clientY - 5, scale: 1, alpha: 1, color: c() }), t.
body.appendChild(a) } function i(e) { var a = t.createElement("style"); a.type =
"text/css"; try { a.appendChild(t.createTextNode(e)) } catch (t) { a.styleSheet.
cssText= e } t.getElementsByTagName("head")[0].appendChild(a) } function c() {
return "rgb(" + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + "," +
~~(255 * Math.random()) + ")" } var s = []; e.requestAnimationFrame = e.
