Reactjs - material UI - How to change the font size of the label in FormControlLabel

To change the font size of the label in FormControlLabel component from Material-UI in React, you can use the Typography component from Material-UI and style it accordingly. Here's how you can achieve this:

Example:

Assume you have a FormControlLabel component and you want to adjust the font size of its label:

import React from 'react'; import FormControlLabel from '@mui/material/FormControlLabel'; import Checkbox from '@mui/material/Checkbox'; import Typography from '@mui/material/Typography'; const MyComponent = () => { return ( <div> <FormControlLabel control={<Checkbox />} label={ <Typography variant="body1" style={{ fontSize: '16px' }}> My Label </Typography> } /> </div> ); }; export default MyComponent;

Explanation:

  1. Import Necessary Components:

    • FormControlLabel and Checkbox are imported from Material-UI to create a labeled checkbox.
    • Typography is imported to style the label text.

  2. Styling the Label:

    • Use the label prop of FormControlLabel to specify a JSX element (Typography in this case).
    • Inside Typography, set the variant prop to "body1" (or any other variant depending on your design guidelines).
    • Use the style prop to apply CSS styles inline. Here, fontSize: '16px' sets the font size to 16 pixels. Adjust this value as needed.

  3. Rendering:

    • In the MyComponent functional component, return the FormControlLabel wrapped in a div (or any other container).

Notes:

  • Ensure that you have installed Material-UI in your project (npm install @mui/material @emotion/react @emotion/styled).
  • Adjust the Typography variant and inline styles (style={{ fontSize: '16px' }}) according to your design requirements.
  • You can also use Material-UI's makeStyles or styled API for more complex styling needs or for consistent styling across your application.

By using Typography within the label prop of FormControlLabel and setting the style prop appropriately, you can effectively change the font size (and other styles) of the label in Material-UI's FormControlLabel component in React.

Examples

  1. React Material UI FormControlLabel change label font size

    • Description: Learn how to customize the font size of the label within a FormControlLabel component using Material UI in a React application.
    • Code:
