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:
Please ref @ant-design/cssinjs.
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 { StyleProvider } from '@ant-design/cssinjs';// Config `hashPriority` to `high` instead of default `low`// Which will remove `:where` wrapperexport 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. Or you can use PostCSS plugin to raise application css selector priority. PostCSS provides many plugins can help on this. e.g:
Raise priority through plugin:
-- .my-btn {++ #root .my-btn {background: red;}
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 { StyleProvider, legacyLogicalPropertiesTransformer } from '@ant-design/cssinjs';// `transformers` provides a way to transform CSS propertiesexport 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;}
In responsive web development, there is a need for a convenient and flexible way to achieve page adaptation and responsive design. The px2remTransformer transformer can quickly and accurately convert pixel units in style sheets to rem units relative to the root element (HTML tag), enabling the implementation of adaptive and responsive layouts.
import { StyleProvider, px2remTransformer } from '@ant-design/cssinjs';const px2rem = px2remTransformer({rootValue: 32, // 32px = 1rem; @default 16});export default () => (<StyleProvider transformers={[px2rem]}><MyApp /></StyleProvider>);
The resulting transformed styles:
.px2rem-box {- width: 400px;+ width: 12.5rem;background-color: green;- font-size: 32px;+ font-size: 1rem;border: 10PX solid #f0f;}@media only screen and (max-width: 600px) {.px2rem-box {background-color: red;- margin: 10px;+ margin: 0.3125rem;}}
| Parameter | Description | Type | Default |
|---|---|---|---|
| rootValue | Font size of the root element | number | 16 |
| precision | Decimal places for the converted value | number | 5 |
| mediaQuery | Whether to convert px in media queries | boolean | false |
For more details, please refer to: px2rem.ts#Options
Since <style /> tag insertion is different from normal DOM in Shadow DOM scenario, you need to use StyleProvider of @ant-design/cssinjs to configure the container property to set the insertion position:
import { StyleProvider } from '@ant-design/cssinjs';import { createRoot } from 'react-dom/client';const shadowRoot = someEle.attachShadow({ mode: 'open' });const container = document.createElement('div');shadowRoot.appendChild(container);const root = createRoot(container);root.render(<StyleProvider container={shadowRoot}><MyApp /></StyleProvider>,);
