## 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;
|
|||
|
}
|
|||
|
}
|
|||
|
```
