I am using material-ui in my project, and I have a Checkbox with a red color.

I would like to show checked Icon when someone would hover on Checkbox only.

It would be hidden when not hovered. I don't seem to find the proper selector for that. I would love any suggestions about what can I do about it.

Some notice points:

• Use Material-UI nesting selector to catch the SVG element since the <Checkbox /> is a lib element which has a static dom structure.

• Use &:hover to catch onMouseOver event.

• Use d: path(value) to pass props d's value to SVG's child element <path />

import React from "react";
import "./styles.css";
import { Checkbox } from "@material-ui/core";
import { makeStyles } from "@material-ui/core/styles";
import AcUnit from "@material-ui/icons/AcUnit";
// import Accessibility from "@material-ui/icons/Accessibility";

const useStyles = makeStyles(theme => ({
  root: {
    background: "#f1f1f1",
    "&:hover": {
      "& span": {
        "& svg": {
          "& path": {
            d:
              "path('M12 2c1.1 0 2 .9 2 2s-.9 2-2 2-2-.9-2-2 .9-2 2-2zm9 7h-6v13h-2v-6h-2v6H9V9H3V7h18v2z')"
          }
        }
      }
    }
  }
}));

export default function App() {
  const classes = useStyles();
  return (
    <div className="App">
      <Checkbox className={classes.root} icon={<AcUnit />} />
    </div>
  );
}

Try it online:

Refer: the <Checkbox /> structure which can be seen in browser

<span
