Extending styled components properties?

Question

H1.js

export default styled.h1`
  margin: 0px;
  color: white;
`;

I want to change the color of this component, and I tried

import H1 from "./H1";

const ColoredH1 = styled(H1)`
    color: "black"
`; 

But this is not changing the color of the H1?

Answer 1

Don't use "black" with quotes , remember that you write CSS within the styled-component , therefore "black" isn't a valid color, although black do.

const ColoredH1 = styled(H1)`
  /* color: "black"; */  /* Invalid Color */

  color: black;          /* Valid Color */
  color: ${"black"}      /* Or use a valid color representation as String */
`;

Answer 2

Put color: black instead of color: "black"

import H1 from "./H1";

const ColoredH1 = styled(H1)`
    color: black;
`; 

For your understanding

const Button = styled.button`
  color: red;
  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border: 2px solid red;
  border-radius: 3px;
`;

const CoralButton = styled(Button)`
  color: coral;
  border-color: coral;
`;
render(
  <div>
    <Button>Normal Button</Button>
    <CoralButton>Tomato Button</CoralButton>
  </div>
);
