How to Upgrade from Bootstrap 4 to Bootstrap 5

Upgrading from Bootstrap 4 to Bootstrap 5 is not an easy operation, since the most recent version of the famous CSS toolkit has several modifications and enhancements. However, you may move your project using these generic steps:

Replace any existing Bootstrap CDN URLs or NPM packages with the new ones. The documentation includes links and packages for Bootstrap 5.

Bootstrap 5 no longer requires jQuery, so remove any references to it from your HTML and JavaScript files.

Update your HTML to include the new Bootstrap 5 classes and components. For example, replace the card-based accordion with the new accordion component, utilize the new offcanvas component for sidebar menus and modals, and apply the.bg-gradient class to gradient-containing components.

Update your Sass variables and mixins with the new Bootstrap 5 syntax and values.

For example, rename the color-yiq () function to color-contrast (), use the new $min-contrast-ratio variable instead of $yiq-contrasted-threshold, and call the new color-level () function instead of theme-color-level.

Test your project in various browsers and devices, and address any issues or errors that arise.
