1. Introduction to Bootstrap 4 Colors

Bootstrap 4 provides a set of predefined color classes that you can apply to different elements in your HTML markup. These color classes allow you to quickly and easily change the text and background colors of various components, such as buttons, headings, alerts, and more. By using Bootstrap 4 colors, you can ensure consistency and visual harmony throughout your website.

Bootstrap 4 offers a variety of text color classes that can be applied to any HTML element. These classes enable you to change the color of the text within an element. For example, you can use the class “text-primary” to display text in a primary color, or “text-danger” to highlight important information in red.

Example:

<p class="text-primary">This is a paragraph with primary text color.</p>

3. Background Colors
