30 Jan 20235 minutes to read

You can customize the React textbox styles such as background-color, text-color and border-color by overriding its default styles.

To change the styles of the floating label, you must override the style to the input element.

index.jsx

import * as React from "react";
import * as ReactDOM from "react-dom";
export default class App extends React.Component {
    constructor(props) {
        super(props);
    }
    render() {
        return (<div className="wrap">
            <label> Normal Input </label>
            <div className="e-input-group">
                <input className="e-input" onFocus={this.floatFocus} onBlur={this.floatBlur} type="text" placeholder="First Name"/>
            </div>
            <label> Floating Input </label>
            <div className="e-float-input">
                <input type="text" required={true}/>
                <span className="e-float-line"/>
                <label className="e-float-text">Last Name</label>
            </div>
        </div>);
    }
    floatFocus(args) {
        args.target.parentElement.classList.add('e-input-focus');
    }
    floatBlur(args) {
        args.target.parentElement.classList.remove('e-input-focus');
    }
}
ReactDOM.render(<App />, document.getElementById('input-container'));
