To import a new font family and override the default font family used by components in Material-UI (previously known as @mui/material), you can follow these steps:

  1. Import and Load the New Font:

First, you need to import the new font into your project. You can do this by adding a link to the font in the <head> section of your HTML file:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Your App</title> <!-- Import the new font --> <link rel="stylesheet" href="path/to/your/font.css"> </head> <body> <!-- Your app content here --> </body> </html>

Make sure to replace "path/to/your/font.css" with the actual path to your font file.

  1. Override Font Family in Material-UI Theme:

Next, you need to override the default font family used by Material-UI components. To do this, you can customize the Material-UI theme using the createTheme function from @mui/material/styles (or @mui/styles for older versions of Material-UI).

Create a custom theme in your application and specify the desired font family:

import { createTheme, ThemeProvider } from '@mui/material/styles'; const theme = createTheme({ typography: { fontFamily: 'Your New Font, sans-serif', // Replace 'Your New Font' with the actual font name }, }); function App() { return ( <ThemeProvider theme={theme}> {/* Your app content here */} </ThemeProvider> ); } export default App;

By setting the typography.fontFamily property in the custom theme, you are overriding the default font family for Material-UI components.

  1. Apply the Custom Theme to Your App:

Wrap your entire application with the ThemeProvider component from Material-UI and provide the theme you created. This will ensure that all Material-UI components within the theme will use the new font family.

With these steps, your Material-UI components should now be using the new font family specified in your custom theme. Keep in mind that the appearance of the components might change depending on the font you choose, so you may need to adjust other styles in your application to ensure a consistent and visually appealing UI.
