 Basic and concise tabs.
 
-:::demo Tabs provide a selective card functionality and it can be achieved by just using `el-tabs` and child element `el-tab-pane`. In these two elements, we provide a list of attributes. The `label` in `el-tab-pane` determines the label of selective cards, and you can write content in the label. In this example, we add a `active-name` attribute indicating the active card in `el-tabs`, which can take a `String` value. In the `el-tab-pane` you can set corresponding `name` attribute, and if there is no `name`, the default sequence is `1`/`2`/`3`/`4`. In this example, the selected card is card 2. If `name` is omitted, setting `active-name` to `2` can reach the same goal.
+:::demo Tabs provide a selective card functionality. By default the first tab is selected as active, and you can activate any tab by setting the `value` attribute.

 ### 基础用法
 
 基础的、简洁的标签页。
 
-:::demo Tabs 组件提供了选项卡功能，只需要使用`el-tabs`和子元素`el-tab-pane`即可，在两个元素中，我们分别提供了一系列的属性来方便使用，`el-tab-pane`中`label`决定了选项卡标题，标签内部写入内容即可。在下例中我们在`el-tabs`中设置了`active-name`属性，接受一个`String`值，表明选中的选项卡，在`el-tab-pane`中可以设置对应的`name`属性，如果没有设置`name`，则默认值为顺序的`1`/`2`/`3`/`4`。例子选中选项卡2，如果不设置`name`，将`active-name`设为`2`，可以达成相同效果。
+:::demo Tabs 组件提供了选项卡功能，默认选中第一个标签页，你也可以通过 `value` 属性来指定当前选中的标签页。
