Installing Tailwind CSS allows developers to use its utility classes to build modern and responsive user interfaces.

Every HTML element is treated as a rectangular box composed of content, padding, border, and margin.

These utilities manage display behavior, positioning, overflow handling, stacking order, and layout flow.

Typography utilities in Tailwind CSS control how text appears in an interface, including font size, font family, font weight, line height, alignment, and style.

Tailwind CSS provides a utility-first color system that allows developers to apply colors directly to elements using predefined class names.

Tailwind CSS provides a mobile-first responsive system using breakpoint prefixes that apply utilities at specific viewport widths.

Using variables helps maintain consistent design systems, simplifies updates, and improves maintainability.

Pseudo-class variants in Tailwind CSS allow utilities to apply styles based on an element’s state or interaction.

Responsive navbars are important because navigation must adapt to different screen sizes, typically showing a hamburger menu on mobile and inline links on desktop.
