title: CSS Compatible
|
|
---
|
|
|
|
Ant Design supports the last 2 versions of modern browsers. If you need to be compatible with legacy browsers, please perform downgrade processing according to actual needs:
|
|
|
|
### Compatible adjustment
|
|
|
|
Ant Design default using CSS-in-JS with `:where` Selector to reduce priority to avoid user additional adjust style cost when updating. If you want to support old browser (or some other CSS framework selector priority conflict like TailwindCSS), you can use `@ant-design/cssinjs` to adjust this behavior (Please note keep version align with antd):
|
|
|
|
```tsx
|
|
import React from 'react';
|
|
import { StyleProvider } from '@ant-design/cssinjs';
|
|
|
|
// Config `hashPriority` to `high` instead of default `low`
|
|
// Which will remove `:where` wrapper
|
|
export default () => (
|
|
<StyleProvider hashPriority="high">
|
|
<MyApp />
|
|
</StyleProvider>
|
|
);
|
|
```
|
|
|
|
It will turn `:where` to class selector:
|
|
|
|
```diff
|
|
-- :where(.css-bAMboO).ant-btn {
|
|
++ .css-bAMboO.ant-btn {
|
|
color: #fff;
|
|
}
|
|
```
|
|
|
|
Note: After turning off the `:where` downgrade, you may need to manually adjust the priority of some styles.
|
|
|
|
### CSS Logical Properties
|
|
|
|
To unify LTR and RTL styles, Ant Design uses CSS logical properties. For example, the original `margin-left` is replaced by `margin-inline-start`, so that it is the starting position spacing under both LTR and RTL. If you need to be compatible with older browsers, you can configure `transformers` through the `StyleProvider` of `@ant-design/cssinjs`:
|
|
|
|
```tsx
|
|
import React from 'react';
|
|
import { StyleProvider, legacyLogicalPropertiesTransformer } from '@ant-design/cssinjs';
|
|
|
|
// `transformers` provides a way to transform CSS properties
|
|
export default () => (
|
|
<StyleProvider transformers={[legacyLogicalPropertiesTransformer]}>
|
|
<MyApp />
|
|
</StyleProvider>
|
|
);
|
|
```
|
|
|
|
When toggled, styles will downgrade CSS logical properties:
|
|
|
|
```diff
|
|
.ant-modal-root {
|
|
-- inset: 0;
|
|
++ top: 0;
|
|
++ right: 0;
|
|
++ bottom: 0;
|
|
++ left: 0;
|
|
}
|
|
```
