前言：

用久了blog会感觉单调。
好吧确实挺单调的。
这次推一个爱心特效的代码，百度上都烂大街了，所以就不注明转载了！
其实用起来还是可以的，自我感觉良好啊。
不说了，直接贴演示：

演示：

Javascript代码:

(function(window,document,undefined){
			var hearts = [];
			window.requestAnimationFrame = (function(){
				return window.requestAnimationFrame ||
				window.webkitRequestAnimationFrame ||
				window.mozRequestAnimationFrame ||
				window.oRequestAnimationFrame ||
				window.msRequestAnimationFrame ||
				function (callback){
					setTimeout(callback,1000/60);
				}
			})();
			init();
			function init(){
				css(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: '';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: absolute;}.heart:after{top: -5px;}.heart:before{left: -5px;}");
				attachEvent();
				gameloop();
			}
			function gameloop(){
				for(var i=0;i<hearts.length;i++){
					if(hearts[i].alpha <=0){
						document.body.removeChild(hearts[i].el);
						hearts.splice(i,1);
						continue;
					}
					hearts[i].y--;
					hearts[i].scale += 0.004;
					hearts[i].alpha -= 0.013;
					hearts[i].el.style.cssText = "left:"+hearts[i].x+"px;top:"+hearts[i].y+"px;opacity:"+hearts[i].alpha+";transform:scale("+hearts[i].scale+","+hearts[i].scale+") rotate(45deg);background:"+hearts[i].color;
				}
				requestAnimationFrame(gameloop);
			}
			function attachEvent(){
				var old = typeof window.οnclick==="function" && window.onclick;
				window.onclick = function(event){
					old && old();
					createHeart(event);
				}
			}
			function createHeart(event){
				var d = document.createElement("div");
				d.className = "heart";
				hearts.push({
					el : d,
					x : event.clientX - 5,
					y : event.clientY - 5,
					scale : 1,
					alpha : 1,
					color : randomColor()
				});
				document.body.appendChild(d);
			}
			function css(css){
				var style = document.createElement("style");
				style.type="text/css";
				try{
					style.appendChild(document.createTextNode(css));
				}catch(ex){
					style.styleSheet.cssText = css;
				}
				document.getElementsByTagName('head')[0].appendChild(style);
			}
			function randomColor(){
				return "rgb("+(~~(Math.random()*255))+","+(~~(Math.random()*255))+","+(~~(Math.random()*255))+")";
			}
		})(window,document);

把它夹在<script>和</script>就可以了.

如果你想在所有界面都使用这个特效:

请先安装Tampermonkey,再安装一下代码：
