How to add multiple classes in Material UI using the classes props?

Material UI is a popular library for building user interfaces in React. It provides a wide range of pre-built components and styling options to make your application look professional and visually appealing. One of the key features of Material UI is the ability to add custom styles to its components using the classes props. In this article, we will explore how to add multiple classes to a Material UI component using the classes props.

When working with Material UI, you might come across scenarios where you need to apply multiple classes to a component. This can be useful when you want to combine the default styles provided by Material UI with your custom styles or when you want to apply different styles based on certain conditions.

There are two main approaches to adding multiple classes in Material UI:

1. Using template literals:

One way to add multiple classes to a Material UI component is by using template literals. Template literals allow you to embed expressions inside a string literal, making it easy to concatenate multiple classes together.

Here’s an example:


import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Button from '@material-ui/core/Button';

const useStyles = makeStyles((theme) => ({
  root: {
    display: 'flex',
    justifyContent: 'center',
    alignItems: 'center',
  },
  primary: {
    backgroundColor: theme.palette.primary.main,
    color: theme.palette.primary.contrastText,
  },
  secondary: {
    backgroundColor: theme.palette.secondary.main,
    color: theme.palette.secondary.contrastText,
  },
}));

const MyButton = () => {
  const classes = useStyles();

  return (
    
  );
};

export default MyButton;

In the above example, we define two classes – primary and secondary – using the makeStyles hook provided by Material UI. We then use template literals to concatenate the root and primary classes together and pass it as the className prop to the Button component.

2. Using array notation:

Another approach to adding multiple classes in Material UI is by using array notation. This approach allows you to pass an array of class names to the className prop, which will be applied to the component in the order they are specified.

Here’s an example:


import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Button from '@material-ui/core/Button';

const useStyles = makeStyles((theme) => ({
  root: {
    display: 'flex',
    justifyContent: 'center',
    alignItems: 'center',
  },
  primary: {
    backgroundColor: theme.palette.primary.main,
    color: theme.palette.primary.contrastText,
  },
  secondary: {
    backgroundColor: theme.palette.secondary.main,
    color: theme.palette.secondary.contrastText,
  },
}));

const MyButton = () => {
  const classes = useStyles();

  return (
    
  );
};

export default MyButton;

In this example, we define the root, primary, and secondary classes using the makeStyles hook. We then pass an array containing the root and primary classes to the className prop of the Button component.

Both approaches will result in the same output, where the component will have multiple classes applied to it.

By using the classes props in Material UI, you can easily add multiple classes to your components, allowing for greater flexibility and customization. Whether you choose to use template literals or array notation, the end result will be a component with the desired styles applied.

That’s it! You now know how to add multiple classes in Material UI using the classes props. Happy coding!
