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):

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:

--  :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:

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:

.ant-modal-root {
-- inset: 0;
++ top: 0;
++ right: 0;
++ bottom: 0;
++ left: 0;
}
