                 CSS3绘制8种超炫的加载动画

    逛前端开发网站的时候，偶尔发现一组非常炫酷的CSS3加载动画，遂迫不及待的做个Demo保存下来。

        这些加载动画用到了CSS3的旋转transform属性，颜色透明度设置和伪元素操作等CSS技术。奇妙的组合，产生了意想不到的效果。

        1.上下起伏波动的加载动画：

  #loader1,
  #loader1:before,
  #loader1:after {
     background: #f2fa08;
     -webkit-animation: load1 1s infinite ease-in-out;
     animation: load1 1s infinite ease-in-out;
     width: 1em;
     height: 4em;
   }
   #loader1:before,
   #loader1:after {
     position: absolute;
     top: 0;
     content: '';
   }
   #loader1:before {
     left: -1.5em;
   }
   #loader1 {
     text-indent: -9999em;
     margin: 50px 50px;
     position: relative;
     float: left;
     font-size: 11px;
     -webkit-animation-delay: 0.16s;
     animation-delay: 0.16s;
   }
   #loader1:after {
     left: 1.5em;
     -webkit-animation-delay: 0.32s;
     animation-delay: 0.32s;
   }
   @-webkit-keyframes load1 {
     0%,
     80%,
     100% {
       box-shadow: 0 0 #f2fa08;
       height: 4em;
     }
     40% {
       box-shadow: 0 -2em #f2fa08;
       height: 5em;
     }
   }
   @keyframes load1 {
     0%,
     80%,
     100% {
       box-shadow: 0 0 #f2ff08;
       height: 4em;
     }
     40% {
       box-shadow: 0 -2em #f2ff08;
       height: 5em;
     }
   }
    2.类似弹簧效果的旋转加载动画：

     此处用到CSS3的transform属性。

     CSS3的变形（transform）属性让元素在一个坐标系统中变形。这个属性包含一系列变形函数，可以移动、旋转和缩放元素。 
      transform属性可用于内联元素和块元素。其默认值为none，表示不元素不进行变形。transform另一个属性值是一系列的<transform-function>。<transform-function>表示一个或多个变形函数，以空格分开；我们可以同时对一个元素进行变形的多种属性操作，如rotate、scale、translate等。以往我们叠加效果都是用逗号(“，”)隔开，但在transform中使用多个transform-function时却需要有空格隔开。
  ● 2D transform常用的transform-function的功能:
      transform属性3D变形（3D transform）模块的一部分，也就是说所有的2D变形函数也包含于3D变形规范中。如此一来，CSS3变形中的函数根据不同的规范略有不同，下面列出的是变形中的2D和3D常用变形函数的功能，简单说明如下： 

      translate()：用来移动元素，可以根据X轴和Ｙ轴坐标重新定位元素位置。在此基础上有两个扩展函数：translateX()和translateY()。

     scale()：用来缩小或放大元素，可以使用元素尺寸发生变化。在此基础上有两个扩展函数：scaleX()和scaleY()。            rotate()：用来旋转元素。

     skew()：用来让元素倾斜。在此基础上有两个扩展函数：skewX()和skewY()。

     matrix()：定义矩阵变形，基于X轴和Y轴坐标重新定位元素位置。
 ● 3D transform常用的transform-function的功能:
      translate3d()：移元素元素，用来指定一个3D变形移动位移量。
      translate()：指定3Ｄ位移在Ｚ轴的位移量。
      scale3d()：用来缩放一个元素。
      scaleZ():指定Z轴的缩放向量。
      rotate3d()：指定元素具有一个三维旋转的角度。
      rotateX()、rotateY()和rotateZ()：让元素具有一个旋转角度。
      perspective()：指定一个透视投影矩阵。
      matrix3d()：定义矩阵变形。

  ● transform-origin属性用来设置变换的原点。示例中代表旋转中心。

     5.大小相同，颜色深浅不一的粒子旋转动画：

   它是运用CSS3的border-radius圆角属性、box-shadow阴影属性等属性制作出来的。

   animation属性设置的参数：

       ● 设置对象所应用的动画名称：load5。

       ● 设置对象动画的持续时间：1.1s。

       ● 设置对象动画的过渡类型：

             ease：动画以低速开始，然后加快，在结束前变慢。

             linear：匀速。

             ease-in：动画以低速开始。

             ease-out：动画以低速结束。

             ease-in-out：动画以低速开始和结束，相对于ease缓慢，速度更均匀。

             step-start：按keyframes设置逐帧显示，第一帧为keyframes设置的第一帧。

             step-end：按keyframes设置逐帧显示，第一帧为样式的初始值。

             steps(<number>[, [ start | end ] ]?)：把keyframes里设置的一帧等分为几帧，start为第一次显示第一帧，end第一次显示样式的初始值，例如：steps(4,start)。

             cubic-bezier(<number>, <number>, <number>, <number>)：在 cubic-bezier 函数中自己的值。可能的值是从 0 到 1 的数值。贝兹曲线限制了首尾两控制点的位置，通过调整中间两控制点的位置可以灵活得到常用的动画效果。

        ● 设置对象动画的循环次数：infinite（无限循环）。

       将动画运行整个过程的分为0%，12.5%，25%，37.5%，50%，62.5%，75%，87.5%，100%这8个阶段，在不同的阶段运用颜色的透明度制作出不同的阴影效果。

      7.横向粒子变动加载动画：

      此处用到了CSS3动画animation属性的animation-fill-mode属性和animation-delay属性。
    ● animation-fill-mode属性规定动画在播放之前或之后，其动画效果是否可见。
        none：不改变默认行为。

        forwards：当动画完成后，保持最后一个属性值（在最后一个关键帧中定义）。

        backwards：在animation-delay所指定的一段时间内，在动画显示之前，应用开始属性值（在第一个关键帧

中定义）。

       both： 向前和向后填充模式都被应用。

     ●  animation-delay属性定义动画何时开始。该属性允许负值，示例中延迟0.16s执行动画。
