css pseudo selectors with material-ui
问题 I have seen in a lot of the material-ui code that they use pseudo selectors in their react styled components. I thought I would try to do it myself and I cannot get it to work. I'm not sure what I am doing wrong or if this is even possible. I am trying to make some css that will offset this element against the fixed header. import React from 'react'; import { createStyles, WithStyles, withStyles, Typography } from '@material-ui/core'; import { TypographyProps } from '@material-ui/core
