transition 平移属性实现 横向整屏 滚动

需要达到效果:

  1. 横向展示商品,默认一行展示5个,超出隐藏,页面一打开,该模块自动横向滚动
  2. 有前进后退按钮,默认隐藏,鼠标移入显示,且动画停止;鼠标移出按钮隐藏,动画重启

效果展示: (由于是截图拼接成的gif, 滚动效果未能展示出来,正常滚动是5s后发生,且很顺滑)

实现原理:

　　1. 使用css3 的 transition 过渡属性完成动画,使动画盒子脱标(脱离标准流), 不影响其他布局, 且方便通过 left 属性进行动画 

　　　　具体就是通过在发生动画的盒子里修改行内属性 left 值,进而发生动画 

　　2. 使用 cubic-bezier 控制变化的速度曲线

实现代码:

贝塞尔曲线:

 cubic-bezier(<x1>,<y1>,<x2>,<y2>),  其实是用4个点确定速度曲线,已知 两个点 (0,0) (1,1) ,我们通过 x1,y1 x2,y2 坐标来控制另外两个点,从而确定速度曲线
