样式化组件：悬停道具

Question

我只想在传递道具时应用 &:hover - 在这种情况下：animated

const AnimationContainer = styled.div`
  transform: translate(0%);
  transition: 0.3s ease-out;

  &:hover { // apply hover only when $(props.animated) is paased
     position: fixed;
     transform: translate(0%, -30%);
     transition: 0.3s ease-out;
   }
`;

有人建议怎么做吗？我想可以为每个以 .. :$(props => props.animated ? ..) 开头的属性应用样式，但是有更简单的解决方案吗？

是啊！像这样：

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

const AnimationContainer = styled.div`
  transform: translate(0%);
  transition: 0.3s ease-out;

  ${props => props.animated && css`
    &:hover {
      position: fixed;
      transform: translate(0%, -30%);
      transition: 0.3s ease-out;
    }
  `}
`

export default AnimationContainer

然后你可以这样使用它：

import AnimationContainer from './path/to/AnimationContainer

// some component here…
  render() {
    return (
      <!-- some JSX element… -->
        <AnimationContainer animated>
          With animation
        </AnimationContainer>
        <AnimationContainer>
          Without animation
        </AnimationContainer>
      <!-- end of some JSX element… -->
    )
  }
