### Handle abnormal image watermarks
|
|
|
|
When using an image watermark and the image loads abnormally, you can add `content` at the same time to prevent the watermark from becoming invalid (since 5.2.3).
|
|
|
|
```typescript jsx
|
|
<Watermark
|
|
height={30}
|
|
width={130}
|
|
content="Ant Design"
|
|
image="https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*lkAoRbywo0oAAAAAAAAAAAAADrJ8AQ/original"
|
|
>
|
|
<div style={{ height: 500 }} />
|
|
</Watermark>
|
|
```
