  children: React.ReactNode
}) {
  return (
    <ThemeProvider
      theme={style.theme as Theme}
      brand={style.brand as Schemes}
      accent={style.accent as Schemes}
      neutral={style.neutral as NeutralColor}
      solid={style.solid as SolidType}
      solidStyle={style.solidStyle as SolidStyle}
      border={style.border as BorderStyle}
      surface={style.surface as SurfaceStyle}
      transition={style.transition as TransitionStyle}
      scaling={style.scaling as ScalingSize}>
      <DataThemeProvider>
        <ToastProvider>

```javascript
<Column fillWidth>
  <Row fillWidth paddingX="xl" paddingY={2} gap="40" border="neutral-alpha-medium" radius="l">
    <Row fillWidth height="64" />
    <Row fillWidth height="64" />
  </Row>
</Column>
```
