Modify the Close Button Icon of React Bootstrap Modal

This article describes how to customize the icon of the close button in React Bootstrap Modal. Since React Bootstrap itself does not directly provide an API to modify the close button icon, we will implement this function by customizing the header and adding event handling methods. This article will provide detailed steps and code examples to help you easily implement the requirement of customizing the close button icon.

The Modal component provided by React Bootstrap is very convenient, but sometimes we need to customize its style, such as modifying the icon of the close button. Since React Bootstrap itself does not provide direct modification of the properties of the close button icon, we need to adopt some tricks to achieve this goal.

Method: Customize the header and add event processing

The core idea is to hide the default close button, then add a custom icon in the Modal Header and bind it to a click event, which is responsible for closing the Modal.

Step 1: Remove the default closeButton property

First, remove the closeButton property from the component. This will hide the default close button.

 <modal.header classname="'modal-head'">
   <modal.title>Cart</modal.title>
</modal.header>

Step 2: Add a custom close icon

Add a custom icon in . You can use any icon library you like, such as Font Awesome, Material Icons, etc. Here we take Font Awesome as an example and assume that you have installed react-fontawesome:

 npm install @fortawesome/react-fontawesome @fortawesome/free-solid-svg-icons

Then introduce the required icons in your component:

 import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { faTimes } from '@fortawesome/free-solid-svg-icons'; // Introduce a close icon

Next, add the icon to :

 <modal.header classname="'modal-head'">
   <modal.title>Cart</modal.title>
   <div style="{{" position: right: adjust icon position top: cursor: onclick="{()"> setShow(false)} // Assume setShow is a function that controls the display status of Modal>
     <fontawesomeicon icon="{faTimes}"></fontawesomeicon>
   </div>
</modal.header>

Step 3: Add a click event handling function

Make sure you have a state variable to control the display and hiding of the Modal. In this example, we assume that this state variable is called show and there is a setShow function to update this state.

Call setShow(false) in the icon's onClick event, which will turn off the Modal.

Complete sample code:

 import React, { useState } from 'react';
import { Modal, Button } from 'react-bootstrap';
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { faTimes } from '@fortawesome/free-solid-svg-icons';

function MyModal() {
  const [show, setShow] = useState(false);

  Return (
    
      <button variant="primary" onclick="{()"> setShow(true)}>
        Launch demo modal
      </button>

      <modal show="{show}" onhide="{()"> setShow(false)}>
        <modal.header classname="'modal-head'">
          <modal.title>Cart</modal.title>
          <div style="{{" position: right: top: cursor: onclick="{()"> setShow(false)}
          >
            <fontawesomeicon icon="{faTimes}"></fontawesomeicon>
          </div>
        </modal.header>
        <modal.body>Woohoo, you're reading this text in a modal!</modal.body>
        <modal.footer>
          <button variant="secondary" onclick="{()"> setShow(false)}>
            Close
          </button>
          <button variant="primary" onclick="{()"> setShow(false)}>
            Save Changes
          </button>
        </modal.footer>
      </modal>
    >
  );
}

export default MyModal;

Notes:

• Style adjustment: Adjust the position and style of the icon according to your specific needs to make sure it looks consistent with the overall style of the Modal.
• Accessibility: Make sure your custom close button is accessible. For example, add the aria-label property to describe the function of a button.
• Icon Library Selection: Select an icon library that suits your project. Font Awesome, Material Icons, etc. are all good choices.

Summarize:

Although React Bootstrap itself does not provide an API that directly modifys the Modal close button icon, we can easily achieve this by customizing the header and adding event handling. This approach is not only flexible, but also gives you complete control over the appearance and behavior of the close button. Hopefully this tutorial will help you successfully customize the close button icon of React Bootstrap Modal.
