Material-ui v1 Input focus style override

I'm trying to override the styling of the Input component when it is on focus via class name overide.

I have tried the following:

const style = theme => ({
  input: {
    width: '20%',
    borderRadius: 4,
    backgroundColor: 'white',
    border: '1px solid #ced4da',
    fontSize: 20,
    '&:focus': {
      width: '40%',
      borderColor: '#80bdff',
      boxShadow: '0 0 0 0.2rem rgba(0,123,255,.25)',
    },
  }
});

class test extends Component {

// UI
render() {
    const {classes} = this.props
    return (
        <AppBar position="static">
            <Toolbar>
                <Input className={classes.input} />
            </Toolbar>
        </AppBar>
    );
}
}

export default withStyles(style)(test);

Thank you

The best way to accomplish that is to override the focused style exposed by the Input component, but using classes instead of class names.

To do so, you should first create a CSS style class specifically for the focused input:

const styles = theme => ({
  input: {
    width: '20%',
    borderRadius: 4,
    backgroundColor: 'white',
    border: '1px solid #ced4da',
    fontSize: 20,
  },
  // Separate this part into it's own CSS class
  inputFocused: {
    width: '40%',
    borderColor: '#80bdff',
    boxShadow: '0 0 0 0.2rem rgba(0,123,255,.25)',
    backgroundColor: "#00FF00",
  },
});

Then override the focused style on the Input like this:

<Input
  className={classes.input}
  classes={{ focused: classes.inputFocused}}
/>

When you join that all together, a full working example would look like this:

import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import Input from 'material-ui/Input';

const styles = theme => ({
  input: {
    width: '20%',
    borderRadius: 4,
    backgroundColor: 'white',
    border: '1px solid #ced4da',
    fontSize: 20,
  },
  // Separate this part into it's own CSS class
  inputFocused: {
    width: '40%',
    borderColor: '#80bdff',
    boxShadow: '0 0 0 0.2rem rgba(0,123,255,.25)',
    backgroundColor: "#00FF00",
  },
});

function Inputs(props) {
  const { classes } = props;
  return (
    <div className={classes.container}>
      <Input
        className={classes.input}
        classes={{ focused: classes.inputFocused}}
      />
    </div>
  );
}

Inputs.propTypes = {
  classes: PropTypes.object.isRequired,
};

export default withStyles(styles)(Inputs);
