Add Univer Icons to your React interface, then adjust their size and colors to match the surrounding controls.

## Install the package

In your React project, install the icon package:

#### npm

```bash
npm install @univerjs/icons
```

#### pnpm

```bash
pnpm add @univerjs/icons
```

#### yarn

```bash
yarn add @univerjs/icons
```

#### bun

```bash
bun add @univerjs/icons
```

## Add an icon to a button

Find a component in the [icon preview](https://docs.univer.ai/guides/icons/all-icons.md) and import it by name. This copy button shows a text label alongside its icon.

```tsx
import { CopyIcon } from '@univerjs/icons'

export function CopyButton({ onCopy }: { onCopy: () => void }) {
  return (
    <button type="button" onClick={onCopy}>
      <CopyIcon aria-hidden="true" />
      <span>Copy</span>
    </button>
  )
}
```

Pass your copy handler through `onCopy`. The icon is decorative because the visible text already names the action.

## Set size and color

Icons inherit the surrounding text color and use `1em` for their size. Set `fontSize` and `color` on the icon to give it a different appearance:

```tsx
import { AddImageIcon } from '@univerjs/icons'

export function ImageToolIcon() {
  return (
    <AddImageIcon
      aria-hidden="true"
      style={{ fontSize: 20, color: '#27272a' }}
    />
  )
}
```

## Set both colors of a two-color icon

For a two-color icon, set the main color with `color` and the accent with `extend.colorChannel1`. This example uses dark gray with a light gray accent:

```tsx
import { PaintBucketDoubleIcon } from '@univerjs/icons'

export function FillToolIcon() {
  return (
    <PaintBucketDoubleIcon
      aria-hidden="true"
      style={{ fontSize: 20, color: '#27272a' }}
      extend={{ colorChannel1: '#d4d4d8' }}
    />
  )
}
```

Multicolor icons, including brand logos, can contain fixed colors. These settings do not replace every color in those icons.

## Keep strokes thin when enlarging icons

If an enlarged icon looks too heavy, try `preserveStrokeWidth`. Supported strokes stay as thin as they are at 16 × 16. Filled shapes are unaffected. Use the stroke control in the preview to check the result before applying it.

```tsx
import { ShapePieIcon } from '@univerjs/icons'

export function ShapeToolIcon() {
  return (
    <ShapePieIcon
      aria-hidden="true"
      preserveStrokeWidth
      style={{ fontSize: 48 }}
    />
  )
}
```

## Give icon-only buttons a name

If you remove the visible button text, add `aria-label="Copy"` to the button and keep `aria-hidden="true"` on the icon. This lets screen readers announce the action.
