## FAQ
|
||
|
||
### 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>
|
||
```
|
||
|
||
### Why `overflow: hidden` style is added since version 5.18.0?
|
||
|
||
User can hide the watermark by setting the container height to 0 through the developer tool in the previous version. To avoid this situation, we added the `overflow: hidden` style to the container. When the container height changes, the content is also hidden. You can override the style to modify this behavior:
|
||
|
||
```tsx
|
||
<Watermark style={{ overflow: 'visible' }} />
|
||
```
