Start using TSS, with or without MUI

Introduced in v4.9

yarn add @mui/material @emotion/styled @emotion/react #Required for MUI
yarn add tss-react
import { tss } from "tss-react/mui";
import Button from "@mui/material/Button";
import { useState }ย from "react";

type Props = {
    className?: string;

export function MyButton(props: Props) {
    const { className } = props;

    const [isClicked, setIsClicked] = useState(false);

    const { classes, cx } = useStyles({ "color": isClicked ? "blue": "red" });

    //Thanks to cx, className will take priority over classes.root ๐Ÿคฉ
    //With TSS you must stop using clsx and use cx instead.
    //More info here: https://github.com/mui/material-ui/pull/31802#issuecomment-1093478971
    return (
            className={cx(classes.root, className)}
            onClick={()=> setIsClicked(true)}
            hello world

const useStyles = tss
    .withParams<{ color: "red" | "blue"; }>()
    .create(({ theme, color })=> ({
        root: {
            // The color of the text is either blue or red depending of 
            // the state fo the component.
            // When the curser is over the button has a black border
            "&:hover": {
                border: '4px solid black'
            // On screens bigger than MD the button will have a big cyan border
            [theme.breakpoints.up("md")]: {
                border: '10px solid cyan'
