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.
