-----------
{: .-three-column}

### Supported

Each section can have the following children:

#### White

- `pre`
- `ul`
- `table`

#### Gray

- `p`
- `h4`

### Prime section
{: .-prime}

This is a section with `{: .-prime}`. Notice the fancy highlight! Great for "getting started" kind of snippets.

### H3 section

Every box is an H3 section. The box will encompass everything inside the body of the H3.

This is a basic section with paragraphs in it.

Code
----
{: .-three-column}

### Basic code

```js
here.is(() => {
  some.code()
})
```

```js
here.is.some.more()
```

Code blocks can be placed one after the other.

See: [Cheatsheets](/)

### Code with headings

#### index.js
{: .-file}

```js
here.is(() => {
  some.code()
})
```

#### other.js
{: .-file}

```js
here.is.some.more()
```

Code blocks can have headings.

### Highlighted lines

```js
app.start(() => {
  const port = app.server.port
  console.log(`Started at ${port}`)
})
```
{: data-line="3"}

Add `{: data-line="3"}` to add line highlights.

### Multiple highlights

```js
app.start(() => {
  const port = app.server.port
  console.log(`Started at ${port}`)
})
```
{: data-line="2,3"}

Add `{: data-line="2,3"}` to add multiple line highlights.

### Setup blocks

```js
import React from 'react'
```
{: .-setup}

```js
class Hello extends React.Component {
  render () {
    return <span>Hello</span>
  }
}
```

Add `{: .-setup}` to a `pre` or `table` or `ul`.

### Long lines

```js
function createNode(nodeName: string, options: { key: string }) {
  return true
}
```

Long lines will have scrollbars.

### Line wrapping

```js
<script>(function(d,s){if(window.Promise&&[].includes&&Object.assign&&window.Map)return;var js,sc=d.getElementsByTagName(s)[0];js=d.createElement(s);js.src='https://cdn.polyfill.io/v2/polyfill.min.js';sc.parentNode.insertBefore(js, sc);}(document,'script'))</script>
