Styled Components with Props

Pass a function to a styled components template literal to adapt it based on its props.

  • Button.jsx
import styled from "styled-components";

const StyledButton = styled.button`
  border: 2px solid #4caf50;
  background-color: #4caf50;
  color: white;
  background-color: ${(props) =>
    props.variant === "outline" ? "#fff" : "#4caf50"};
  color: ${(props) => (props.variant === "outline" ? "#4caf50" : "#fff")};
  padding: 15px 20px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 12px;
  cursor: pointer;
  transition: 0.5s all ease-out;
`;
export default StyledButton;
Enter fullscreen mode Exit fullscreen mode
  • App.jsx
function App() {
  return (
    <div className="App">
      <StyledButton>Styled Button</StyledButton>
      <div>
        <br />
      </div>
      <StyledButton variant="outline">Styled Button</StyledButton>
    </div>

Styled Components using Props

Extending Styles

To easily make a new component that inherits the styling of another, just wrap it in the styled() constructor.

  • Button.js
import styled from "styled-components";

export const StyledButton = styled.button`
  border: 2px solid #4caf50;
  background-color: ${(props) =>
    props.variant === "outline" ? "#fff" : "#4caf50"};
  color: ${(props) => (props.variant === "outline" ? "#4caf50" : "#fff")};
  padding: 15px 20px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 12px;
  cursor: pointer;
  transition: 0.5s all ease-out;
`;

export const FancyButton = styled(StyledButton)`
  background-image: linear-gradient(to right, #f6d365 0%, #fda085 100%);
  border: none;
`;
Enter fullscreen mode Exit fullscreen mode
  • App.jsx
function App() {
  return (
    <div className="App">
      <StyledButton>Styled Button</StyledButton>
      <div>
        <br />
      </div>
      <StyledButton variant="outline">Styled Button</StyledButton>
      <div>
        <br />
      </div>
      <FancyButton as="a">Fancy Button</FancyButton>
      {/* as - is a polymorphic prop => pass anchor tag */}
    </div>
  );
}
Enter fullscreen mode Exit fullscreen mode
