List of icons

Examples

Basic Two-tone icon and colorful icon Custom Icon Use iconfont.cn Multiple resources from iconfont.cn

API

Common Icon

Property Description Type Default Version
className The className of Icon string -
rotate Rotate by n degrees (not working in IE9) number -
spin Rotate icon with animation boolean false
style The style properties of icon, like fontSize and color CSSProperties -
twoToneColor Only supports the two-tone icon. Specify the primary color string (hex color) -

We still have three different themes for icons, icon component name is the icon name suffixed by the theme name.

import { StarOutlined, StarFilled, StarTwoTone } from '@ant-design/icons';

<StarOutlined />
<StarFilled />
<StarTwoTone twoToneColor="#eb2f96" />

Custom Icon

component The component used for the root node ComponentType<CustomIconComponentProps> -
rotate Rotate degrees (not working in IE9) number -
spin Rotate icon with animation boolean false
style The style properties of icon, like fontSize and color CSSProperties -

About SVG icons

We introduced SVG icons in version 3.9.0, replacing font icons. This has the following benefits:

  • Complete offline usage of icons, without dependency on a CDN-hosted font icon file (No more empty square during downloading and no need to deploy icon font files locally either!)
  • Much more display accuracy on lower-resolution screens
  • The ability to choose icon color
  • No need to change built-in icons with overriding styles by providing more props in component

More discussion of SVG icon reference at #10353.

⚠️ Given the extra bundle size caused by all SVG icons imported in 3.9.0, we will provide a new API to allow developers to import icons as needed, you can track #12011 for updates.

While you wait, you can use webpack plugin from the community to chunk the icon file.

The properties theme, component and twoToneColor were added in 3.9.0. The best practice is to pass the property theme to every <Icon /> component.

import { MessageOutlined } from '@ant-design/icons';

<MessageOutlined style={{ fontSize: '16px', color: '#08c' }} />;

All the icons will render to <svg>. You can still set style and className for size and color of icons.

<Icon type="message" style={{ fontSize: '16px', color: '#08c' }} theme="outlined" />

Set TwoTone Color

When using the two-tone icons, you can use the static methods getTwoToneColor() and setTwoToneColor(colorString) to specify the primary color.

import { getTwoToneColor, setTwoToneColor } from '@ant-design/icons';

setTwoToneColor('#eb2f96');
getTwoToneColor(); // #eb2f96

Custom Font Icon

We added a createFromIconfontCN function to help developer use their own icons deployed at iconfont.cn in a convenient way.

This method is specified for iconfont.cn.

import React from 'react';
import ReactDOM from 'react-dom/client';
import { createFromIconfontCN } from '@ant-design/icons';

const MyIcon = createFromIconfontCN({
  scriptUrl: '//at.alicdn.com/t/font_8d5l8fzk5b87iudi.js', // generate in iconfont.cn
});

ReactDOM.createRoot(mountNode).render(<MyIcon type="icon-example" />);

It creates a component that uses SVG sprites in essence.

The following options are available:

Property Description Type Default Version
extraCommonProps Define extra properties to the component { [key: string]: any } {}
scriptUrl The URL generated by iconfont.cn project. Support string[] after @ant-design/icons@4.1.0 string | string[] -

The property scriptUrl should be set to import the SVG sprite symbols.

See iconfont.cn documents to learn about how to generate scriptUrl.

Custom SVG Icon

You can import SVG icon as a react component by using webpack and @svgr/webpack. @svgr/webpack's options reference.

// webpack.config.js
module.exports = {
  // ... other config
  test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
  use: [
    {
      loader: 'babel-loader',
    },
    {
      loader: '@svgr/webpack',
      options: {
        babel: false,
        icon: true,
      },
    },
  ],
};
import React from 'react';
import ReactDOM from 'react-dom/client';
import Icon from '@ant-design/icons';
import MessageSvg from 'path/to/message.svg'; // path to your '*.svg' file.
// in create-react-app:
// import { ReactComponent as MessageSvg } from 'path/to/message.svg';

ReactDOM.createRoot(mountNode).render(<Icon component={MessageSvg} />);

The following properties are available for the component:

Property Description Type Readonly Version
className The computed class name of the svg element string -
fill Define the color used to paint the svg element string currentColor
height The height of the svg element string | number 1em
style The computed style of the svg element CSSProperties -
width The width of the svg element string | number 1em
