The issue of pseudo elements not functioning properly in Material-UI makeStyles with React.js has been a frustrating

The use of pseudo elements in Material-UI makeStyles is not functioning correctly.

innerBox: {
        borderRadius: "10px",
        background: "#fff",
        boxShadow: "0px 1px 3px 0px rgba(0, 0, 0, 0.36)",
        maxHeight: "50px",
        "& ::before": {
            content: "anything"
        }
    }

Answer №1

It appears that the issue lies within your selector. Instead of using & ::before, you should try using &:before

innerBox: {
    borderRadius: "10px",
    background: "#fff",
    boxShadow: "0px 1px 3px 0px rgba(0, 0, 0, 0.36)",
    maxHeight: "50px",
    "&:before": {
        content: "anything"
    }
}
