Transition过渡
transition-property  要运动的样式  （all || [attr] || none）
transition-duration 运动时间
transition-delay 延迟时间
transition-timing-function 运动形式 
ease：（逐渐变慢）默认值
linear：（匀速）
ease-in：(加速)
ease-out：（减速）
ease-in-out：（先加速后减速）
cubic-bezier 贝塞尔曲线（ x1, y1, x2, y2 ） http://matthewlein.com/ceaser/

过渡完成事件 
Webkit内核： obj.addEventListener('webkitTransitionEnd',function(){},false);
firefox: obj.addEventListener('transitionend',function(){},false);

<script>
	var oBox=document.getElementById("box");
	oBox.οnclick=function()
	{
		this.style.width=this.offsetWidth+100+"px";
	};
	addEnd(oBox,function(){
		alert("end");	
	});
	function addEnd(obj,fn)
	{
		obj.addEventListener('WebkitTransitionEnd',fn,false);
		obj.addEventListener('transitionend',fn,false);
	}
</script>
//结束回调-永无止境
<script>
	var oBox=document.getElementById("box");
	oBox.οnclick=function()
	{
		this.style.width=this.offsetWidth+100+"px";
	};
	addEnd(oBox,function(){
		this.style.width=this.offsetWidth+100+"px";
	});
	function addEnd(obj,fn)
	{
		obj.addEventListener('WebkitTransitionEnd',fn,false);
		obj.addEventListener('transitionend',fn,false);
	}
</script>

//解决上述问题
<script>
	var oBox=document.getElementById("box");
	oBox.οnclick=function()
	{
		this.style.width=this.offsetWidth+100+"px";
		addEnd(oBox,end);
	};
	function end()
	{
		this.style.width=this.offsetWidth+100+"px";
		removeEnd(this,end);
	}
	function addEnd(obj,fn)
	{
		obj.addEventListener('WebkitTransitionEnd',fn,false);
		obj.addEventListener('transitionend',fn,false);
	}
	function removeEnd(obj,fn)
	{
		obj.removeEventListener('WebkitTransitionEnd',fn,false);
		obj.removeEventListener('transitionend',fn,false);
	}
</script>

2D变换
transform
rotate()  旋转函数 取值度数
deg  度数
Transform-origin 旋转的基点
skew() 倾斜函数 取值度数 
skewX()
skewY()
scale() 缩放函数 取值 正数、负数和小数
scaleX()
scaleY()
translate() 位移函数
translateX()
translateY()
Transform 执行顺序问题 — 后写先执行

//倾斜的导航

li{float:left;width:100px; text-align:center;height:30px;border:1px solid #fff; background:Red; font:12px/30px "宋体"; -webkit-transform:skewX(30deg); }

matrix(a,b,c,d,e,f) 矩阵函数
通过矩阵实现缩放
x轴缩放 a=x*a    c=x*c     e=x*e;
y轴缩放 b=y*b   d=y*d     f=y*f;
通过矩阵实现位移
x轴位移: e=e+x
y轴位移: f=f+y
通过矩阵实现倾斜
x轴倾斜: c=Math.tan(xDeg/180*Math.PI)
y轴倾斜: b=Math.tan(yDeg/180*Math.PI)
matrix(a,b,c,d,e,f) 矩阵函数
通过矩阵实现旋转
a=Math.cos(deg/180*Math.PI); 
b=Math.sin(deg/180*Math.PI);
c=-Math.sin(deg/180*Math.PI);
d=Math.cos(deg/180*Math.PI);
变换兼容IE9以下IE版本只能通过矩阵来实现
filter: progid:DXImageTransform.Microsoft.Matrix( M11= 1, M12= 0, M21= 0 , M22=1,SizingMethod='auto expand');
IE下的矩阵没有E和F两个参数 M11==a; M12==c; M21==b; M22==d
