## FAQ
### Responsive Tabs
There are 3 cases when handling responsive tabs:
We get hidden tabs through [useVisibleRange.ts](https://github.com/react-component/tabs/blob/master/src/hooks/useVisibleRange.ts).
If enconter the third case, in order to make tabs responsive, some tabs should be hidden.
So we minus `addSize` when calculating `basicSize` manully, even though there's no addNode in container.
In this way, case 3 turns to case 2, tabs become stable again.
