-**Note:** Children of `Affix` must not have the property `position: absolute`, but you can set `position: absolute` on `Affix` itself:
+**Note:** Children of `Affix` can not be `position: absolute`, but you can set `Affix` as `position: absolute`:
 
 ```jsx

-## FAQ
-
-### Affix bind container with `target`, sometime move out of container.
-
-We don't listen window scroll for performance consideration. You can add listener if you still want: <https://codesandbox.io/s/2xyj5zr85p>

-### Affix 使用 `target` 绑定容器时，元素会跑到容器外。
-
-从性能角度考虑，我们只监听容器滚动事件。如果希望任意滚动，你可以在窗体添加滚动监听：<https://codesandbox.io/s/2xyj5zr85p>
