Installation

# with npm

# with yarn

Getting Started

// Create a Title component that'll render an <h1> tag with some styles
const Title = styled.h1`
  font-size: 1.5em;
  text-align: center;
  color: palevioletred;
`;

// Create a Wrapper component that'll render a <section> tag with some styles
const Wrapper = styled.section`
  padding: 4em;
  background: papayawhip;
`;

// Use Title and Wrapper like any other React component – except they're styled!
render(
  <Wrapper>
    <Title>
      Hello World!
    </Title>
  </Wrapper>
);

Adapting based on props

const Button = styled.button`
  /* Adapt the colors based on primary prop */
  background: ${props => props.primary ? "palevioletred" : "white"};
  color: ${props => props.primary ? "white" : "palevioletred"};

  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border: 2px solid palevioletred;
  border-radius: 3px;
`;

render(
  <div>
    <Button>Normal</Button>
    <Button primary>Primary</Button>
  </div>
);

Extending Styles

// The Button from the last section without the interpolations
const Button = styled.button`
  color: palevioletred;
  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border: 2px solid palevioletred;
  border-radius: 3px;
`;

// A new component based on Button, but with some override styles
const TomatoButton = styled(Button)`
  color: tomato;
  border-color: tomato;
`;

render(
  <div>
    <Button>Normal Button</Button>
    <TomatoButton>Tomato Button</TomatoButton>
  </div>
);

Attaching additional props

Overriding .attrs

const Input = styled.input.attrs(props => ({
  type: "text",
  size: props.size || "1em",
}))`
  border: 2px solid palevioletred;
  margin: ${props => props.size};
  padding: ${props => props.size};
`;

// Input's attrs will be applied first, and then this attrs obj
const PasswordInput = styled(Input).attrs({
  type: "password",
})`
  // similarly, border will override Input's border
  border: 2px solid aqua;
`;

render(
  <div>
    <Input placeholder="A bigger text input" size="2em" />
    <br />
    {/* Notice we can still use the size attr from Input */}
    <PasswordInput placeholder="A bigger password input" size="2em" />
  </div>
);

Animations

import styled, { keyframes } from 'styled-components';

// Create the keyframes
const rotate = keyframes`
  from {
    transform: rotate(0deg);
  }

  to {
    transform: rotate(360deg);
  }
`;

// Here we create a component that will rotate everything we pass in over two seconds
const Rotate = styled.div`
  display: inline-block;
  animation: ${rotate} 2s linear infinite;
  padding: 2rem 1rem;
  font-size: 1.2rem;
`;

render(
  <Rotate>&lt; 💅🏾 &gt;</Rotate>
);

Theme

// Define our button, but with the use of props.theme this time
const Button = styled.button`
  font-size: 1em;
  margin: 1em;
  padding: 0.25em 1em;
  border-radius: 3px;

  /* Color the border and text with theme.main */
  color: ${props => props.theme.main};
  border: 2px solid ${props => props.theme.main};
`;

// We are passing a default theme for Buttons that arent wrapped in the ThemeProvider
Button.defaultProps = {
  theme: {
    main: "palevioletred"
  }
}

// Define what props.theme will look like
const theme = {
  main: "mediumseagreen"
};

render(
  <div>
    <Button>Normal</Button>

    <ThemeProvider theme={theme}>
      <Button>Themed</Button>
    </ThemeProvider>
  </div>
);

    color: ${props => props.theme.colors.text};
  `}
/>
<Button
