Unable to adjust the size of the font within a text field component in Material UI

I'm currently delving into learning Material UI and am faced with the task of enlarging the text field on my webpage. Despite embedding styles along with the field, the height, width, and other properties change except for the size. Here's the snippet of my code:

const styles = {
        container: {
            display: 'flex',
            flexWrap: 'wrap',
        },
        textField: {
            // marginLeft: theme.spacing.unit,
            // marginRight: theme.spacing.unit,
            width: 300,
            margin: 100,
            fontSize: 50 //??? Doesnt work
        }
    }

Below is the stateless React component:

const Searchbox = (props) => {

        const { classes } = props;

        return (
            <TextField
                onKeyDown={props.onKeyDown}
                id="with-placeholder"
                label="Add ID"
                placeholder="ID"
                className={classes.textField}
                margin="normal"
                autoFocus={true}
                helperText={"Add an existing ID or select "}
            />
        );
    };

    export default withStyles(styles)(Searchbox);

I understand that applying styles in this CSS-in-JS approach should be straightforward.

However, I'm facing difficulty overriding the base font size for my text field. Any assistance would be greatly appreciated.

Answer №2

Exploring the features of the TextField API, it allows for applying styles to the InputProps that in turn style the input element.

Check out the code snippet below:

const styles = {
  container: {
    display: 'flex',
    flexWrap: 'wrap',
  },
  textField: {
    width: 300,
    margin: 100,
  },
  //font size styling
  resize:{
    fontSize:50
  },
}

<TextField
  id="with-placeholder"
  label="Add id"
  placeholder="id"
  InputProps={{
    classes: {
      input: classes.resize,
    },
  }}
  className={classes.textField}
  margin="normal"
  autoFocus={true}
  helperText={"Add an existing id or select "} />

Answer №3

My current version is 3.8.1 and I believe I have a simpler approach to solve this issue.

When dealing with the TextField

inputProps={{
  style: {fontSize: 15} 
}}

However, adjusting the lineHeight may also be necessary for a nicer visual presentation.

Make use of the sx property and specify the target input base class as MuiInputBase-input

 <TextField
          sx={{
            '.MuiInputBase-input': { fontSize: '1.25rem' },
          }}
/>

Answer №5

To adjust the text size before (label) and after (input text) user interaction with the TextField component, I followed these steps:

<TextField
  id="MyTextField"
  InputProps={{
    classes: {
      input: classes.formTextInput
    }
  }}
  InputLabelProps={{
    classes: {
      root: classes.formTextLabel
    }
  }}
/>

Answer №6

<TextField inputStyle={styles.textField} />

Below is the complete code snippet: 

import React from 'react';
import TextField from 'material-ui/TextField';

const styles = {
    textField: {
    fontSize: 50, //works!
 }
}

const Searchbox = (props) => {
return (
    <TextField
        onKeyDown={props.onKeyDown}
        id="with-placeholder"
        label="Add id"
        placeholder="id"
        inputStyle={styles.textField}
        margin="normal"
        autoFocus={true}
        helperText={"Add an existing id or select "}
    />
    );
};
export default Searchbox;

Answer №7

<TextField
    type="text"
    className={classes.financing_input}
    placeholder={this.props.CustomerInfoData.phone}
    name="phone"
    id="fixInputSize" //Works 
    onChange={this.handleChange}
/>

//within the stylesheet
#fixInputSize{
  font-family: Roboto;
  font-size: 11px;
}

Answer №8

If you're utilizing Sass for styling purposes, there's another neat trick you can try out.

<Textfield className="styled-input" />

Next, in your Sass file, include the following code:

.styled-input {
  width: ....px;

  fieldset { /* additional styles like border-radius */ }

  input {
    font-size: 1.2rem;
  }
}

                name="lastName"
                {...register("lastName", {
                  required: "Last Name is required.",
                })}
                error={Boolean(errors.lastName)}
                helperText={errors.lastName?.message}
              />

Answer №11

Experiment with the use of the inputStyle property

inputStyle --> Customize the appearance of the TextField's input component. For single-line inputs: specify the style for the input element. For multi-line inputs: define the styling for the textarea container.

    <TextField
      inputStyle={{ fontSize: "50px" }}
      hintText="Hint Text"
    />
