Step-by-Step Guide

Bootstrap offers a wide range of color and background classes which can be used to change the text color, background color, link color, etc. It includes color classes for typography, background, borders, and other components.

Bootstrap Color Classes

Bootstrap includes classes for setting text and link colors. The classes .text-{color} and .text-{context} can be used to set the color of text, where {color} can be any of Bootstrap’s color names (like danger, success, dark, etc.) and {context} is for contextual classes (like primary, secondary, info, etc.)

Bootstrap Background Classes

Bootstrap also includes background color classes. The .bg-{color} and .bg-{context} classes are used to set the background color of an element, where {color} can be any of Bootstrap's color names and {context} is for contextual classes.

Code Examples
