React-Bootstrap is a popular library that provides pre-built UI components for React applications. One of the commonly used components is the ‘Input’ component, which allows users to input data in forms or interact with the application. By default, the ‘Input’ component in React-Bootstrap has a standard size, which may not always be ideal for certain design requirements.
Before proceeding, ensure that you have the following prerequisites installed.
Npm or yarn
Node.js
React
React bootstrap
If you don't have the React project setup, you can refer to this tutorial: How to Set Up React on Windows.
To begin, make sure you have React-Bootstrap installed in your project. You can install it using npm or yarn.
npm install react-bootstrap bootstrap //using npm// ORyarn add react-bootstrap bootstrap //using yarn
Once installed, import the required dependencies in your javascript file, where you want to add the ‘Input’ component.
import React from 'react';import { Form } from 'react-bootstrap';
Also, import Bootstrap in index.js
import 'bootstrap/dist/css/bootstrap.min.css'; // Import the Bootstrap CSS
React-Bootstrap provides a size prop that allows you to modify the size of the ‘Input’ component. By setting the size prop to sm (small), you can create a smaller version of the ‘Input’ component. You can add this line where you want to create ‘Input’ component.
<Form.Control size="sm" type="text" placeholder="Small input" />
In the example above, we set the size prop to sm to create a smaller ‘Input’ component. You can apply this size modification to various types of inputs, such as text, password, and number, by changing the type prop accordingly.
If you want to further customize the appearance of the smaller ‘Input’ component, you can use CSS to apply additional styling. React-Bootstrap provides class names that you can use to target specific components and modify their styles.
Create a CustomInput.css file and add custom CSS there.
.custom-input{font-size: 16px !important;margin: 1em 0em !important;width: 50% !important;}
!important adds more importance to the property and helps override the default CSS of React-Bootstrap.
custom-inputis an arbitrary class name used in this example. You can change it to any other valid class name that fits your naming convention and preferences.
Now, import the CSS file in the file you want to add custom styling.
import './CustomInput.css';
Now you can use className prop to add custom CSS to your component.
<Form.ControlclassName="custom-input"size="sm"type="text"placeholder="Small input"/>
Run the application by the following command.
npm start
To run the sample application, execute the following code.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta
name="viewport"
content="width=device-width, initial-scale=1, shrink-to-fit=no"
/>
<meta name="theme-color" content="#000000" />

Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.
