Is there a way to style the border color and text color of <TextField/> in Material-UI without using makeStyles

问题

Is it possible to style Material-UI without using the makeStyles feature, for example, css? Just trying to understand how Material-UI style works.

The red style on the bottom is the style I'm trying to achieve with simple css here.

Below is an example of how to customize the various colors in an outlined select using simple CSS.

styles.css

.customSelect {
  width: 200px;
}
.customSelect .MuiInputLabel-root {
  color: red;
}
.customSelect .MuiInputBase-input {
  color: green;
}
.customSelect .MuiOutlinedInput-notchedOutline {
  border-color: red;
}
.customSelect:hover .MuiOutlinedInput-notchedOutline {
  border-color: orange;
}
.customSelect
  .MuiOutlinedInput-root.Mui-focused
  .MuiOutlinedInput-notchedOutline {
  border-color: purple;
}
.customSelectMenu .MuiMenuItem-root {
  color: blue;
}

App.js

import React from "react";
import "./styles.css";
import TextField from "@material-ui/core/TextField";
import MenuItem from "@material-ui/core/MenuItem";

export default function App() {
  const [value, setValue] = React.useState("");
  return (
    <TextField
      className="customSelect"
      label="Sale Type"
      required
      select
      value={value}
      onChange={event => setValue(event.target.value)}
      variant="outlined"
      SelectProps={{ MenuProps: { className: "customSelectMenu" } }}
    >
      <MenuItem value={1}>Sale Type 1</MenuItem>
      <MenuItem value={2}>Sale Type 2</MenuItem>
    </TextField>
  );
}
