Bootstrap Utilities

Bootstrap utilities are a powerful set of classes that make styling your website easier and faster without needing to write custom CSS. Let’s dive into the basics!

What Are Bootstrap Utilities?
Bootstrap utilities are predefined CSS classes that you can apply directly to HTML elements to control their appearance or behavior. These utilities are handy for things like spacing, alignment, text, and more. Instead of writing your own CSS, you can use these classes to style your elements quickly.

Common Bootstrap Utilities
Here are some of the most commonly used Bootstrap utilities:

Spacing (Margin and Padding)

m- and p- classes control margin and padding, respectively.
Example: mt-3 adds margin to the top, mb-4 adds margin to the bottom, and p-2 adds padding all around.

Text Alignment

Use classes like text-left, text-center, and text-right to align text.

Display

The d- classes control the display property of an element, like d-none (hide the element) or d-block (make it a block-level element).

Flexbox

Bootstrap’s d-flex class turns an element into a flex container, and you can use other flex utilities to control layout.
Example:

distributes items with space between them.

Colors

The bg- and text- classes apply background and text colors.

Borders

Use border utilities to add or remove borders from elements.
