Theming

Allows you to create a custom theme and apply it globally across all components in your application using a ThemeProvider.

{
  import { createMuiTheme, ThemeProvider } from '@material-ui/core/styles';
  const theme = createMuiTheme({
    palette: {
      primary: {
        main: '#556cd6',
      },
      secondary: {
        main: '#19857b',
      },
    },
  });
  function App() {
    return (
      <ThemeProvider theme={theme}>
        <YourComponent />
      </ThemeProvider>
    );
  }
}

CSS-in-JS

Provides a way to define styles using JavaScript, which allows for dynamic styling and access to props and theme in styles.

{
  import { makeStyles } from '@material-ui/core/styles';
  const useStyles = makeStyles({
    root: {
      background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
      border: 0,
      borderRadius: 3,
      boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
      color: 'white',
      height: 48,
      padding: '0 30px',
    },
  });
  function StyledComponent() {
    const classes = useStyles();
    return <button className={classes.root}>Styled Button</button>;
  }
}
