import styled from 'styled-components'

const Tab = ({ onClick, isSelected, children }) => {
    const TabWrapper = styled.li`
    display: flex;
    align-items: center;
    justify-content: center;
    padding: 100px;
    margin: 1px;
    font-size: 3em;
    color: ${props => (isSelected ? `white` : `black`)};
    background-color: ${props => (isSelected ? `black` : `#C4C4C4`)};
    cursor: ${props => (isSelected ? 'default' : `pointer`)};
`

    return <TabWrapper onClick={onClick}>{children}</TabWrapper>
}


export default Tab

我相信文档所说的是，您应该避免将您的样式包含在呈现组件中：

这样做

const StyledWrapper = styled.div`
  /* ... */
`

const Wrapper = ({ message }) => {
  return <StyledWrapper>{message}</StyledWrapper>
}

而不是这个

const Wrapper = ({ message }) => {
  // WARNING: THIS IS VERY VERY BAD AND SLOW, DO NOT DO THIS!!!
  const StyledWrapper = styled.div`
    /* ... */
  `

  return <StyledWrapper>{message}</StyledWrapper>
}

const Button = styled.button`
  /* Adapt the colours 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;
`;

// class X extends React.Component {
//  ...

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

// }

const TabWrapper = styled.li`
  display: flex;
  align-items: center;
  justify-content: center;
  padding: 100px;
  margin: 1px;
  font-size: 3em;
  color: ${props => (props.isSelected ? `white` : `black`)};
  background-color: ${props => (props.isSelected ? `black` : `#C4C4C4`)};
  cursor: ${props => (props.isSelected ? 'default' : `pointer`)};
`;

const Tab = ({ onClick, isSelected, children }) => {
  return <TabWrapper onClick={onClick}>{children}</TabWrapper>
}

const X = <Tab onClick={() => console.log('clicked')} isSelected>Some Children</Tab>
