transform样式动画
=============

设置transform属性对组件进行旋转、缩放、移动和倾斜。

#### 设置静态动画

创建一个正方形并旋转90°变成菱形，并用下方的长方形把菱形下半部分遮盖形成屋顶，设置长方形translate属性值为(150px,-150px)确定坐标位置形成门，再使用position属性使横纵线跟随父组件（正方形）移动到指定坐标位置，接着设置scale属性使父子组件一起变大形成窗户大小，最后使用skewX属性使组件倾斜后设置坐标translate(200px,-710px)得到烟囱。

#### 设置平移动画

小球下降动画，改变小球的Y轴坐标实现小球下落，在下一段时间内减小Y轴坐标实现小球回弹，让每次回弹的高度逐次减小直至回弹高度为0，就模拟出了小球下降的动画。

#### 设置旋转动画

设置不同的原点位置（transform-origin）改变元素所围绕的旋转中心。rotate3d属性前三个参数值分别为X轴、Y轴、Z轴的旋转向量，第四个值为旋转角度，旋转角度可为负值，负值则代表旋转方向为逆时针方向。

transform-origin变换对象的原点位置，如果仅设置一个值，另一个值为50%，若设置两个值第一个值表示X轴的位置，第二个值表示Y轴的位置。

#### 设置缩放动画

设置scale样式属性实现涟漪动画，先使用定位确定元素的位置，确定坐标后创建多个组件实现重合效果，再设置opacity属性改变组件不透明度实现组件隐藏与显示，同时设置scale值使组件可以一边放大一边隐藏，最后设置两个组件不同的动画执行时间，实现扩散的效果。

设置scale3d中X轴、Y轴、Z轴的缩放参数实现动画。

设置transform属性值后，子元素会跟着父元素一起改变，若只改变父元素其他属性值时（如：height，width），子元素不会改变。

#### 设置matrix属性

matrix是一个参数为六个值的矩阵，6个值分别代表：scaleX, skewY, skewX, scaleY, translateX, translateY。下面示例中设置了matrix属性为matrix(1,0,0,1,0,200)使组件移动和倾斜。

transform可以设置多个值并且多个值可同时设置，下面案例中展示同时设置缩放（scale），平移（translate），旋转（rotate）属性时的动画效果。

*   当设置多个transform时，后续的transform值会把前面的覆盖掉。若想同时使用多个动画样式可用复合写法，例：transform: scale(1) rotate(0) translate(0,0)。
    
*   transform进行复合写法时，变化样式内多个样式值顺序的不同会呈现不一样的动画效果。
    
*   transform属性设置的样式值要一一对应，若前后不对应，则该动画不生效。若设置多个样式值则只会呈现出已对应值的动画效果。
