A prime example of poor focus management is not resetting the focus on the triggering element upon closing a modal dialog. Unfortunately, ensuring that all interactive elements are accessible via the keyboard is a task that is all-too-often overlooked by web developers. One of the key components of accessibility is keyboard navigation, allowing users who have difficulty using a mouse to navigate your application.
