css - 我想在 Emotion/styled 组件中重用某些 CSS 属性

Question

import styled from '@emotion/styled';

type ColorProps = {
    Coloured: boolean,
}

const BoxStyled = styled.div`
    ${(props:ColorProps) => 
    props.Coloured ? {
    
    background: "#304f8f",
    border: "1.85px solid #304f8f",
    color: "white",
    width: "4rem",
    height: "2.5rem",
    padding:"0 11px" 
} :
{
    
    border: "1.98px solid #2c8090",
    width: "4rem",
    height: "2.5rem",
    padding:"0 11px" 
}
}`

在 BoxStyled 中，我不想写两次 width: "4rem"、height: "2.5rem"、padding:"0 11px"我该如何实现这一点？

Answer 1

使用css制作样式变量。

import { css } from 'styled-components'

const reuse = css`
  width: 4rem;
  height: 2.5rem;
  padding: 0 11px;
`

const StyleA = styled.div`
  background-color: black;
  ${reuse}
`

const StyleB = styled.div`
  background-color: red;
  ${reuse}
`
