emotion 9 升级到 10 了,所以9的用法就不总结了,官网上介绍的很详细。
点击传送门查看9升到10都变了哪些。
几点建议:
(1)10中尽量只用import styled from '@emotion/styled/macro'
原因是调试方便,可以方便地找到css文件。(需安装"@emotion/core": "^10.0.7","@emotion/styled": "^10.0.7")
但是nwb@0.23.0环境中babel的版本是6,使用import styled from '@emotion/styled/macro'会报错
Error: Can't resolve 'fs' in 'C:workNewk2-ui ode_modulesconvert-source-map'
暂时用import styled from '@emotion/styled';
eg:
import styled from '@emotion/styled' let SomeComp = styled.div({ color: 'hotpink' }) let AnotherComp = styled.div` color: ${props => props.color}; ` render( <SomeComp> <AnotherComp color="green" /> </SomeComp> )
