## 使用CSS动画
CSS动画为网页增添了美感。 CSS动画可以将CSS样式转换为另一种CSS样式。
要创建CSS动画序列,我们在CSS的`animation`属性中有不同的子属性:
*   `animation-delay`
*   `animation-direction`
*   `animation-duration`
*   `animation-iteration-count`
*   `animation-name`
*   `animation-play-state`
*   `animation-timing-function`
*   `animation-fill-mode`
### 用于在屏幕上移动文本的CSS动画序列示例
在HTML部分中,我们将有一个带有类`container`的`div`和一个带有文本`Hello World`的`h3` :
```html
 
    
 Hello World ! 
 
  
```
对于CSS部分:
```css
.container { 
    /* We will define the width, height and padding of the container */ 
    /* The text-align to center */ 
    width: 400px; 
    height: 60px; 
    padding: 32px; 
    text-align: center; 
 
    /* Use the animation `blink` to repeat infinitely for a time period of 2.5s*/ 
    animation-duration: 2.5s; 
    animation-iteration-count: infinite; 
    animation-direction: normal; 
    animation-name: blink; 
 
    /* The same can be written shorthand as     */ 
    /* --------------------------------------   */ 
    /* animation: 2.5s infinite normal blink;   */ 
 } 
 @keyframes blink { 
    0%, 100% {              /* Defines the properties at these frames */ 
        background: #333; 
        color: white; 
    } 
 
    50% {                   /* Defines the properties at these frames */ 
        background: #ccc; 
        color: black; 
        border-radius: 48px; 
    } 
 } 
```
