 As options can be passed via data attributes or JavaScript, you can append an option name to `data-bs-`, as in `data-bs-animation="{value}"`. Make sure to change the case type of the option name from “_camelCase_” to “_kebab-case_” when passing the options via data attributes. For example, use `data-bs-custom-class="beautifier"` instead of `data-bs-customClass="beautifier"`.

 With Bootstrap 4, we once again rewrote the project to account for two key architectural changes: a migration to Sass and the move to CSS’s flexbox. Our intention is to help in a small way to move the web development community forward by pushing for newer CSS properties, fewer dependencies, and new technologies across more modern browsers.
 
-Our latest release, Bootstrap 5, focuses on improving v4’s codebase with as few major breaking changes as possible. We improved existing features and components, removed support for older browsers, dropped jQuery for regular JavaScript, and embraced more future-friendly technologies like CSS custom properties as part of our tooling.

 Whenever possible, we'll assign CSS variables at the base component level (e.g., `.navbar` for navbar and its sub-components). This reduces guessing on where and how to customize, and allows for easy modifications by our team in future updates.
