## Card 卡片
|
||
将信息聚合在卡片容器中展示。
|
||
|
||
### 基础用法
|
||
|
||
|
||
包含标题，内容和操作。
|
||
|
||
:::demo Card 组件包括`header`和`body`部分，`header`部分需要有显式具名 slot 分发，同时也是可选的。
|
||
```html
|
||
<el-card class="box-card">
|
||
<div slot="header" class="clearfix">
|
||
<span>卡片名称</span>
|
||
<el-button style="float: right; padding: 3px 0" type="text">操作按钮</el-button>
|
||
</div>
|
||
<div v-for="o in 4" :key="o" class="text item">
|
||
{{'列表内容 ' + o }}
|
||
</div>
|
||
</el-card>
|
||
|
||
<style>
|
||
.text {
|
||
font-size: 14px;
|
||
}
|
||
|
||
.item {
|
||
margin-bottom: 18px;
|
||
}
|
||
|
||
.clearfix:before,
|
||
.clearfix:after {
|
||
display: table;
|
||
content: "";
|
||
}
|
||
.clearfix:after {
|
||
clear: both
|
||
}
|
||
|
||
.box-card {
|
||
width: 480px;
|
||
}
|
||
</style>
|
||
```
|
||

|
||
|
||
### 简单卡片
|
||
|
||
卡片可以只有内容区域。
|
||
|
||
:::demo
|
||
```html
|
||
<el-card class="box-card">
|
||
<div v-for="o in 4" :key="o" class="text item">
|
||
{{'列表内容 ' + o }}
|
||
</div>
|
||
</el-card>
|
||
|
||
<style>
|
||
.text {
|
||
font-size: 14px;
|
||
}
|
||
|
||
.item {
|
||
padding: 18px 0;
|
||
}
|
||
|
||
.box-card {
|
||
width: 480px;
|
||
}
|
||
</style>
|
||
```
|
||

|
||
|
||
### 带图片
|
||
|
||
可配置定义更丰富的内容展示。
|
||
|
||
:::demo 配置`body-style`属性来自定义`body`部分的`style`，我们还使用了布局组件。
|
||
```html
|
||
<el-row>
|
||
<el-col :span="8" v-for="(o, index) in 2" :key="o" :offset="index > 0 ? 2 : 0">
|
||
<el-card :body-style="{ padding: '0px' }">
|
||
<img src="https://shadow.elemecdn.com/app/element/hamburger.9cf7b091-55e9-11e9-a976-7f4d0b07eef6.png" class="image">
|
||
<div style="padding: 14px;">
|
||
<span>好吃的汉堡</span>
|
||
<div class="bottom clearfix">
|
||
<time class="time">{{ currentDate }}</time>
|
||
<el-button type="text" class="button">操作按钮</el-button>
|
||
</div>
|
||
</div>
|
||
</el-card>
|
||
</el-col>
|
||
</el-row>
|
||
|
||
<style>
|
||
.time {
|
||
font-size: 13px;
|
||
color: #999;
|
||
}
|
||
|
||
.bottom {
|
||
margin-top: 13px;
|
||
line-height: 12px;
|
||
}
|
||
|
||
.button {
|
||
padding: 0;
|
||
float: right;
|
||
}
|
||
|
||
.image {
|
||
width: 100%;
|
||
display: block;
|
||
}
|
||
|
||
.clearfix:before,
|
||
.clearfix:after {
|
||
display: table;
|
||
content: "";
|
||
}
|
||
|
||
.clearfix:after {
|
||
clear: both
|
||
}
|
||
</style>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
currentDate: new Date()
|
||
};
|
||
}
|
||
}
|
||
</script>
|
||
```

### 卡片阴影
|
||
|
||
可对阴影的显示进行配置。
|
||
|
||
:::demo 通过`shadow`属性设置卡片阴影出现的时机：`always`、`hover`或`never`。
|
||
```html
|
||
<el-row :gutter="12">
|
||
<el-col :span="8">
|
||
<el-card shadow="always">
|
||
总是显示
|
||
</el-card>
|
||
</el-col>
|
||
<el-col :span="8">
|
||
<el-card shadow="hover">
|
||
鼠标悬浮时显示
|
||
</el-card>
|
||
</el-col>
|
||
<el-col :span="8">
|
||
<el-card shadow="never">
|
||
从不显示
|
||
</el-card>
|
||
</el-col>
|
||
</el-row>
|
||
```
