Adding an input-group-addon class in Bootstrap 4 to enhance the form

Embarking on a new project, I made the decision to upgrade to Bootstrap 4. While working on creating a form, I noticed that the 'input-group-addon' class was not functioning properly.

I am perplexed as to why this is the case, as the class works flawlessly when using bootstrap-4-alpha. Upon inspection, I could not find any reference to this class in bootstrap.css, bootstrap-grid.css, or bootstrap-reboot.css.

Could it be that they have removed this class? Is there something I am overlooking?

The differences between bootstrap, bootstrap-grid, and bootstrap-reboot are quite confusing to me at the moment, but perhaps that is a question for another time.

If you're still using Bootstrap 4 alpha, it's starting to feel a bit dated now. However, here's the solution to your query:

In Bootstrap 4, the classes .input-group-addon and .input-group-btn have been replaced with .input-group-prepend and .input-group-append. You need to specifically use either append or prepend, which simplifies the CSS significantly. When placing buttons within an append or prepend, wrap text in .input-group-text.
