### How to import

Semi support `Highlight` component since v2.24.0

```jsx import
import { Highlight } from '@douyinfe/semi-ui';
```


### Basic usage

You can specify keywords to be highlighted with `searchWords` and source text with `sourceString`

<Notice title='Attension'>
The Highlight component will split the text into multiple independent inline elements. Any CSS layout that splits the text flow (such as flex layout) may break the highlighted text. To prevent the highlighted content from being split into different rows or columns by the browser, please wrap the Highlight component with a wrapper element as needed.
</Notice>

```jsx live=true dir="column"
import React from 'react';
import { Highlight } from '@douyinfe/semi-ui';

() => {
    const sourceString = 'From Semi Design，To Any Design. Quickly define your design system and apply it to design drafts and code';
    const searchWords = ['Any Design', 'Semi Design'];
    
    return (<h2>
        <Highlight sourceString={sourceString} searchWords={searchWords} />
    </h2>);
};
```

### Specify highlight style

By default, the highlighted text will have its own text style, the text color is black, and the background color is `--semi-yellow-4`.  
In dark mode, the text color is white, and the background color is `--semi-yellow-2`.  
When you need to customize different highlight styles, you can specify them through `highlightClassName`, `highlightStyle`

```jsx live=true dir="column"
import React from 'react';
import { Highlight } from '@douyinfe/semi-ui';

() => {
    const sourceString = 'From Semi Design，To Any Design. Quickly define your design system and apply it to design drafts and code';
    const searchWords = ['Any Design', 'Semi Design'];
    
    return (<h2>
        <Highlight
            sourceString={sourceString}
            searchWords={searchWords}
            highlightStyle={{
                borderRadius: 6,
                marginLeft: 4,
                marginRight: 4,
                paddingLeft: 4,
                paddingRight: 4,
                backgroundColor: 'rgba(var(--semi-teal-5), 1)',
                color: 'rgba(var(--semi-white), 1)'
            }}
        />
    </h2>);
};
```

### Use Different Styles for Different Texts
After v2.71.0, it supports using different highlight styles for different highlighted texts.
The `searchWords` is a string array by default. When an array of objects is passed in, the highlighted text can be specified through `text`, and the `className` and `style` can be specified separately at the same time. 

```jsx live=true dir="column"
import React from 'react';
import { Highlight } from '@douyinfe/semi-ui';

() => {
    return (
        <h2>
            <Highlight
                component='span'
                sourceString='From Semi Design，To Any Design. Quickly define your design system and apply it to design drafts and code'
                searchWords={[
                    { text: 'Semi', style: { backgroundColor: 'rgba(var(--semi-teal-5), 1)', color: 'rgba(var(--semi-white), 1)', padding: 4 }, className: 'keyword1' },
                    { text: 'Quickly', style: { backgroundColor: 'var(--semi-color-primary)', color: 'rgba(var(--semi-white), 1)', padding: 4 }, className: 'keyword2' },
                    { text: 'code', style: { backgroundColor: 'rgba(var(--semi-violet-5), 1)', color: 'rgba(var(--semi-white), 1)', padding: 4 }, className: 'keyword3' },
                ]}
                highlightStyle={{ borderRadius: 4 }}
            />
        </h2>
    );
};
```


### Specify the highlight tag

Semi will wrap the text matching searchWords in sourceString with mark tag by default, you can also re-specify the tag through `component`

```jsx live=true dir="column"
import React from 'react';
import { Highlight } from '@douyinfe/semi-ui';

() => {
    const sourceString = 'From Semi Design，To Any Design. Quickly define your design system and apply it to design drafts and code';
    const searchWords = ['Any Design', 'Semi Design'];
    
    return (<h2>
        <Highlight
            sourceString={sourceString}
            searchWords={searchWords}
            component='strong'
        />
    </h2>);
};
```
