How do I style a component that has `styled-components` nested in it?

Question

I am new to styled-components. I'm trying to set styles for MyComponent to apply to styled-component.

export const Relative = styled.div`
  position: relative;
`

export const Container = ({ children }) => {
  return <Relative>
    <AnotherComponent/>
    {children}
  </Relative>
}

export const MyComponent = () => <Container>/* */</Container>

How can I use styled-components to style a Container inside MyComponent without editing MyComponent?

When you're using styled(YourComponent), assuming YourComponent is a normal Component and not already a styled-component, this will automatically provide the className property to the component. You simple need to put that somewhere.

export const Relative = styled.div`
  position: relative;
`

export const Container = ({ children }) => {
  return (
    <Relative>
      <AnotherComponent/>
      {children}
    </Relative>
  )
}

export const MyComponent = ({ className, children }) => {
  return (
    <div className={className}>
      <Container>
        {children}
      </Container>
    </div>
  )
}

export const CustomMyComponent = styled(MyComponent)`
  // Styles inside here will be applied to the root element of MyComponent
`;
