CSS3下Animations动画库示例

一、CSS3动画库 Animatable

什么是css3动画?

通过 CSS3，我们能够创建动画，这可以在许多网页中取代动画图片、Flash 动画以及 JavaScript。

CSS3带来了圆角，半透明，阴影，渐变，多背景图等新的特征，轻松实现了设计稿中常见的图层样式，用简洁的代码替代图片，代替了多余的空标签。

background-color

.background-color { background:#708090; animation:1s ease 0s alternate none infinite background-color;}
@keyframes background-color{
    from{ background:#708090;}
    to{ background:#000;}
}

background-position

background-position 属性设置背景图像的起始位置，默认值：0% 0%，效果等同于left top

范例一：

.background-position-1 { background-image: -moz-linear-gradient(-45deg, transparent 25%, black 25%, black 50%, transparent 50%, transparent 75%, black 75%, black); background-size:50px 50px; animation:1s ease 0s alternate none infinite background-position-1;}
@keyframes background-position-1{
  from{ background-position:0 0;}
  to{ background-position:100% 100%;}
}
1

范例二：

.background-position-2 { background-color: #E04332; background-repeat: repeat-x; background-size: 24px 300px; background-image: linear-gradient(-45deg, slategray 25%, transparent 25%), linear-gradient(45deg, transparent 75%, slategray 75%), linear-gradient(45deg, slategray 25%, transparent 25%), linear-gradient(-45deg, transparent 75%, slategray 75%); animation:1s ease 0s alternate none infinite background-position-2;}
@keyframes background-position-2{
  from{ background-position:3px 0, 3px 0, 15px -150px, 15px -150px;}
  to{ background-position:3px -70px, 3px -70px, 15px -80px, 15px -80px;}
}

background-size

background-size 属性规定背景图片的尺寸。在 CSS3 之前，背景图片的尺寸是由图片的实际尺寸决定的。在CSS3中，可以规定背景图片的尺寸，这就允许我们在不同的环境中重复使用背景图片。

.background-size {background-image: repeating-radial-gradient(transparent, transparent 9px, black 11px, black 20px); background-position:center; animation:1s ease 0s alternate none infinite background-size;}
@keyframes background-size{
    from{ background-size:5px 5px;}
    to{ background-size:150px 150px;}
}

范例二
