Bootstrap Tooltip Reference

I. Introduction

Bootstrap tooltips are lightweight, easily customizable, and are used to display brief information about a particular element when a user hovers over it. Tooltips offer an effective way of providing additional context without overwhelming the user interface. This makes them a valuable feature in web development, improving user experience by keeping essential information accessible yet unobtrusive.
