## 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
<div class="container">
<h3> Hello World ! </h3>
</div>
```
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;
}
}
```
