# Language highlighting

Docsify uses [Prism](https://prismjs.com) to highlight code blocks in your pages. Prism supports the following languages by default:

* Markup - `markup`, `html`, `xml`, `svg`, `mathml`, `ssml`, `atom`, `rss`
* CSS - `css`
* C-like - `clike`
* JavaScript - `javascript`, `js`

Support for [additional languages](https://prismjs.com/#supported-languages) is available by loading the language-specific [grammar files](https://cdn.jsdelivr.net/npm/prismjs@1/components/) via CDN:

```html
<script src="//cdn.jsdelivr.net/npm/prismjs@1/components/prism-bash.min.js"></script>
<script src="//cdn.jsdelivr.net/npm/prismjs@1/components/prism-php.min.js"></script>
```

To enable syntax highlighting, wrap each code block in triple backticks with the [language](https://prismjs.com/#supported-languages) specified on the first line:

````
```html
<p>This is a paragraph</p>
<a href="//docsify.js.org/">Docsify</a>
```

```bash
echo "hello"
```

```php
function getAdder(int $x): int 
{
    return 123;
}
```
````

The above markdown will be rendered as:

```html
<p>This is a paragraph</p>
<a href="//docsify.js.org/">Docsify</a>
```

```bash
echo "hello"
```

```php
function getAdder(int $x): int 
{
    return 123;
}
```
