## Will you provide Sass/Stylus(etc.) style files in addition to the Less style files currently included?

There is currently no plan to add support for Sass/Stylus(etc.) style files, but using tools on Google you can easily convert the provided Less files to your desired style format.

## `Select Dropdown DatePicker TimePicker Popover Popconfirm` disappears when I click another popup component inside it. How do I resolve this?

This is an old bug that has been fixed since `v3.11.x`. If you're using an older version, you can use `<Select getPopupContainer={trigger => trigger.parentElement}>` to render a component inside Popover. (Or other `getXxxxContainer` props)

Related issue: [#3487](https://github.com/ant-design/ant-design/issues/3487) [#3438](https://github.com/ant-design/ant-design/issues/3438)

## How do I prevent `Select Dropdown DatePicker TimePicker Popover Popconfirm` scrolling with the page?

Use `<Select getPopupContainer={trigger => trigger.parentElement}>` ([API reference](/components/select/#Select-props)) to render a component inside the scroll area. If you need to config this globally in your application, try `<ConfigProvider getPopupContainer={trigger => trigger.parentElement}>` ([API reference](/components/config-provider/#API))

And make sure that parentElement is `position: relative` or `position: absolute`.

## How do I modify the default theme of Ant Design?

See: https://ant.design/docs/react/customize-theme .

## How do I modify `Menu`/`Button`(etc.)'s style?

While you can override a component's style, we don't recommend doing so. antd is not only a set of React components, but also a design specification as well.

## How to use other data-time lib like Moment.js?

Please refer to [Use custom date library](/docs/react/use-custom-date-library).

## It doesn't work when I change `defaultValue` dynamically.

The `defaultXxxx` (e.g. `defaultValue`) of `Input`/`Select`(etc...) only works on the first render. It is a specification of React. Please read [React's documentation](https://facebook.github.io/react/docs/forms.html#controlled-components).

## Why does modifying props in mutable way not trigger a component update?

antd use shallow compare of props to optimize performance. You should always pass the new object when updating the state. Please ref [React's document](https://reactjs.org/docs/thinking-in-react.html)

## After I set the `value` of an `Input`/`Select`(etc.) component, the value cannot be changed by user's action.

Try `onChange` to change `value`, and please read [React's documentation](https://reactjs.org/docs/forms.html#controlled-components).

## Components are not vertically aligned when placed in single row.

Try [Space](https://ant.design/components/space/) component to make them aligned.

## antd overrides my global styles

Yes, antd is designed to help you develop a complete background application. To do so, we override some global styles for styling convenience, and currently these cannot be removed or changed. More info at https://github.com/ant-design/ant-design/issues/4331 .

Alternatively, follow the instructions in [How to avoid modifying global styles?](/docs/react/customize-theme#How-to-avoid-modifying-global-styles)

## I cannot install `antd` and `antd`'s dependencies in mainland China.

To potentially solve this, try [npm mirror china](https://npmmirror.com) and [cnpm](https://github.com/cnpm/cnpm).

## I set `dependencies.antd` as the git repository in `package.json`, but it doesn't work.

Please install `antd` with either npm or yarn.

## `message` and `notification` is lower case, but other components are capitalized. Is this a typo?

No, `message` is just a function, not a React Component, thus it is not a typo that it is in lower case.

## `antd` doesn't work well in mobile.

Please check [Ant Design Mobile](http://mobile.ant.design) as a possible solution, as `antd` has not been optimized to work well on mobile. You can also try the [react-component](https://github.com/react-component/) repositories which start with 'm-' 'rn-', which are also designed for mobile.

## Does `antd` supply standalone files like 'React'?

Yes, you can [import `antd` with script tag](https://ant.design/docs/react/introduce#Import-in-Browser), but we recommend using `npm` to import `antd`, as it is simple and easy to maintain.

## How do I extend antd's components?

If you need some features which should not be included in antd, try to extend antd's component with [HOC](https://gist.github.com/sebmarkbage/ef0bf1f338a7182b6775). [more](https://medium.com/@dan_abramov/mixins-are-dead-long-live-higher-order-components-94a0d2f9e750#.eeu8q01s1)

## How do I fix dynamic styles while using a Content Security Policy (CSP)?

You can configure `nonce` by [ConfigProvider](/components/config-provider/#Content-Security-Policy).

## When I set `mode` to `DatePicker`/`RangePicker`, why can I not select a year or month anymore?

In a real world development, you may need a `YearPicker`, `MonthRangePicker` or `WeekRangePicker`. You are trying to add `mode` to `DatePicker`/`RangePicker` expected to implement those pickers. However, the `DatePicker`/`RangePicker` cannot be selected and the panels won't close now.

- Reproduction link: https://codesandbox.io/s/dank-brook-v1csy
- Same issues：[#15572](https://github.com/ant-design/ant-design/issues/15572), [#16436](https://github.com/ant-design/ant-design/issues/16436), [#11938](https://github.com/ant-design/ant-design/issues/11938), [#11735](https://github.com/ant-design/ant-design/issues/11735), [#11586](https://github.com/ant-design/ant-design/issues/11586), [#10425](https://github.com/ant-design/ant-design/issues/10425), [#11053](https://github.com/ant-design/ant-design/issues/11053)

Like [the explaination](https://github.com/ant-design/ant-design/issues/11586#issuecomment-429189877) explains, this is because `<DatePicker mode="year" />` does not equal the `YearPicker`, nor is `<RangePicker mode="month" />` equal to `MonthRangePicker`. The `mode` property was added to support [showing time picker panel in DatePicker](https://github.com/ant-design/ant-design/issues/5190) in antd 3.0, which simply controls the displayed panel, and won't change the original date picking behavior of `DatePicker`/`RangePicker` (for instance you will still need to click date cell to finish selection in a `DatePicker`, whatever the `mode` is).

Likewise，`disabledDate` [cannot work on year/month panels](https://github.com/ant-design/ant-design/issues/9008#issuecomment-358554118) of `<DatePicker mode="year/month" />`, but only on cells of date panel.

### Workaround

You can refer to [this article](https://juejin.im/post/5cf65c366fb9a07eca6968f9) or [this article](https://www.cnblogs.com/zyl-Tara/p/10197177.html), using `mode` and `onPanelChange` to encapsulate a `YearPicker` or `MonthRangePicker` for your needs.

Or you can simply upgrade to [antd@4.0](https://github.com/ant-design/ant-design/issues/16911), in which we [added more XxxPickers](https://github.com/ant-design/ant-design/issues/4524#issuecomment-480576884) to meet those requirements, and `disabledDate` could be effect on those pickers too.

## message/notification/Modal.confirm lost styles when set `prefixCls` on ConfigProvider?

Static methods like message/notification/Modal.confirm are not using the same render tree as `<Button />`, but rendered to independent DOM node created by `ReactDOM.render`, which cannot access React context from ConfigProvider. Consider two solutions here:

1. Replace original usages with [message.useMessage](/components/message/#components-message-demo-hooks), [notification.useNotification](/components/notification/#Why-I-can-not-access-context,-redux,-ConfigProvider-locale/prefixCls-in-notification) and [Modal.useModal](/components/modal/#Why-I-can-not-access-context,-redux,-ConfigProvider-locale/prefixCls-in-Modal.xxx).

2. Use `ConfigProvider.config` to config `prefixCls` globally.

```js
ConfigProvider.config({
  prefixCls: 'ant',
});
```

## Why shouldn't I use component internal props or state with ref?

You should only access the API by official doc with ref. Directly access internal `props` or `state` is not recommended which will make your code strong coupling with current version. Any refactor will break your code like refactor with [Hooks](https://reactjs.org/docs/hooks-intro.html) version, delete or rename internal `props` or `state`, adjust internal node constructor, etc.

## How to spell Ant Design correctly?

- ✅ **Ant Design**: Capitalized with space, for the design language.
- ✅ **antd**: all lowercase, for the React UI library.
- ✅ **ant.design**：For ant.design website url.

Here are some typical wrong examples:

- ❌ AntD
- ❌ antD
- ❌ Antd
- ❌ ant design
- ❌ AntDesign
- ❌ antdesign
- ❌ Antdesign
