How to Remove overflow: hidden from Bootstrap 5 Modal in React Applications

When developing a React application with Bootstrap, one common issue developers encounter is the modal's handling of the overflow property. Specifically, when using a modal from Bootstrap 5, you may notice that upon opening it for the second time, your body element still carries the style="overflow: hidden; padding-right: 17px;" as well as the class modal-open. This is problematic because it prevents users from scrolling the page even after they close the modal. In this post, we will explore how to resolve this issue effectively.

Understanding the Problem

The Issue

When you trigger the Bootstrap modal, Bootstrap's JavaScript automatically adds the class modal-open to the body. This is intended to prevent background scrolling while the modal is open. However, if the modal is not properly closed or if there is some JavaScript logic that doesn't toggle properly, this class and the associated styles can persist—leading to a frustrating user experience.

Effects

Users are unable to scroll the main content after the modal is closed.

The body remains in the overflow: hidden state, disabling access to content that may be needed.

Solution: Override Bootstrap Styling

Fortunately, Bootstrap's CSS is easily overridden, allowing you to customize the behavior of these modal classes. Here’s how you can handle the overflow: hidden issue on your own.

Step-by-Step Instructions

Create Custom CSS: Open your project's CSS or SCSS file where you can write custom styles for Bootstrap components. This might be a file like styles.css or a specific SCSS file if you’re using SCSS.

Add Custom Styles: Insert the following code snippet to override the default overflow property for the modal:

Save and Test: After saving your changes, test your modal again. Open and close it a few times to ensure that the body’s overflow property is returning to normal, allowing for smooth scrolling once the modal is closed.

Summary

By intercepting Bootstrap's default behavior with a few lines of custom CSS, you can re-enable scrolling in your React application even after using the modal multiple times. Just remember to always check for any persistent styles from third-party frameworks like Bootstrap and know that you have the power to change them to suit your needs.

Give this method a try in your own projects, and say goodbye to unwanted scrolling restrictions caused by Bootstrap 5 modals!
