How do I pass a prop from a Parent styled component to its children's styled components no matter how deep

I have these styled components:

import styled, { css } from 'styled-components'

const Container = styled.div`
  background-color: ${props => props.theme === "light" ? "hsl(0, 0%, 98%)" : "hsl(235, 24%, 19%)" };
  border-radius: 4px;
  box-shadow: ${props => props.theme === "light" ? "0px 35px 50px -15px rgba(194, 195, 214, 0.5)" : "0px 35px 50px -15px rgba(0, 0, 0, 0.5)" };
`

const Footer = styled.footer`
  padding: 25px;
  display: flex;
  align-items: center;
  justify-content: space-between;
  color: ${props => props.theme === "light" ? "hsl(236, 9%, 61%)" : "hsl(234, 11%, 52%)" };
  font-size: 14px;
`

const Nav = styled.nav`
  display: flex;
  align-items: center;
  justify-content: space-between;
  color: inherit;
`

const NavItem = styled.a`
  cursor: pointer;
  display: inline-block;
  color: inherit;

  &:hover {
    color: ${props => props.theme === "light" ? "hsl(235, 19%, 35%)" : "hsl(236, 33%, 92%)" };
  }

  &:not(:last-of-type) {
    margin-right: 15px;
  }

  ${({ active }) =>
    active &&
    css`
      color: hsl(220, 98%, 61%);
    `
  }
`

const ClearList = styled.p`
  color: inherit;
  cursor: pointer;

  &:hover {
    color: ${props => props.theme === "light" ? "hsl(235, 19%, 35%)" : "hsl(234, 39%, 85%)" };
  }
`

And I have this component called TodoList with a theme props that get passed to the styled components like this:

const TodoList = ({ theme }) => {
  return (
    <Container theme={theme}>
      <Footer theme={theme}>
        <p>5 items left</p>
        <Nav>
          <NavItem theme={theme}>All</NavItem>
          <NavItem theme={theme}>Active</NavItem>
          <NavItem theme={theme}>Completed</NavItem>
        </Nav>
        <ClearList theme={theme}>Clear Completed</ClearList>
      </Footer>
    </Container>
  )
}

export default TodoList

How do I call the theme props only once in the Container element and make it accessible to all the child elements such as Clearlist, NavItems and Footer without explicitly passing them

Thank you

You can solve this issue by using ThemeProvider

visit this link https://styled-components.com/docs/advanced

Example

// Define our button, but with the use of props.theme this time
const Button = styled.button`
  color: ${props => props.theme.fg};
  border: 2px solid ${props => props.theme.fg};
  background: ${props => props.theme.bg};

  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border-radius: 3px;
`;

// Define our `fg` and `bg` on the theme
const theme = {
  fg: "palevioletred",
  bg: "white"
};

// This theme swaps `fg` and `bg`
const invertTheme = ({ fg, bg }) => ({
  fg: bg,
  bg: fg
});

render(
  <ThemeProvider theme={theme}>
    <div>
      <Button>Default Theme</Button>

      <ThemeProvider theme={invertTheme}>
        <Button>Inverted Theme</Button>
      </ThemeProvider>
    </div>
  </ThemeProvider>
);
