## Timeline 时间线
可视化地呈现时间流信息。
### 基础用法
Timeline 可拆分成多个按照时间戳正序或倒序排列的 activity时间戳是其区分于其他控件的重要特征使⽤时注意与 Steps 步骤条等区分。
:::demo
```html
<div class="block">
<div class="radio">
排序:
<el-radio-group v-model="reverse">
<el-radio :label="true">倒序</el-radio>
<el-radio :label="false">正序</el-radio>
</el-radio-group>
</div>
<el-timeline :reverse="reverse">
<el-timeline-item
v-for="(activity, index) in activities"
:key="index"
:timestamp="activity.timestamp">
{{activity.content}}
</el-timeline-item>
</el-timeline>
</div>
<script>
export default {
data() {
return {
reverse: true,
activities: [{
content: '活动按期开始',
timestamp: '2018-04-15'
}, {
content: '通过审核',
timestamp: '2018-04-13'
}, {
content: '创建成功',
timestamp: '2018-04-11'
}]
};
}
};
</script>
```

### ⾃定义节点样式
可根据实际场景⾃定义节点尺⼨、颜⾊,或直接使⽤图标。
:::demo
```html
<div class="block">
<el-timeline>
<el-timeline-item
v-for="(activity, index) in activities"
:key="index"
:icon="activity.icon"
:type="activity.type"
:color="activity.color"
:size="activity.size"
:timestamp="activity.timestamp">
{{activity.content}}
</el-timeline-item>
</el-timeline>
</div>
<script>
export default {
data() {
return {
activities: [{
content: '支持使用图标',
timestamp: '2018-04-12 20:46',
size: 'large',
type: 'primary',
icon: 'el-icon-more'
}, {
content: '支持自定义颜色',
timestamp: '2018-04-03 20:46',
color: '#0bbd87'
}, {
content: '支持自定义尺寸',
timestamp: '2018-04-03 20:46',
size: 'large'
}, {
content: '默认样式的节点',
timestamp: '2018-04-03 20:46'
}]
};
}
};
</script>
```

### ⾃定义时间戳
当内容在垂直⽅向上过⾼时,可将时间戳置于内容之上。
:::demo
```html
<div class="block">
<el-timeline>
<el-timeline-item timestamp="2018/4/12" placement="top">
<el-card>
<h4>更新 Github 模板</h4>
<p>王小虎 提交于 2018/4/12 20:46</p>
</el-card>
</el-timeline-item>
<el-timeline-item timestamp="2018/4/3" placement="top">
<el-card>
<h4>更新 Github 模板</h4>
<p>王小虎 提交于 2018/4/3 20:46</p>
</el-card>
</el-timeline-item>
<el-timeline-item timestamp="2018/4/2" placement="top">
<el-card>
<h4>更新 Github 模板</h4>
<p>王小虎 提交于 2018/4/2 20:46</p>
</el-card>
</el-timeline-item>
</el-timeline>
</div>
```
