What is Tailwind CSS, and how is it different from traditional CSS frameworks like Bootstrap?

The Tailwind CSS is an utility-first CSS framework to create custom user interfaces quickly. In contrast to other frameworks based on traditional CSS such as Bootstrap, which contains a set of pre-designed components and themes, Tailwind instead focuses on utility classes on a low level and enables designers to create designs right in their markup in a fast and precise manner.

Key Differences Between Tailwind CSS and Bootstrap:

Feature
Tailwind CSS
Bootstrap

Approach
Utility-first (atomic classes)
Component-based (predefined components)

Customization
Highly customizable via config file
Limited to theming options or custom CSS

Design Freedom
Full design control; no enforced style
Prescriptive styles that follow a design system

Learning Curve
Steeper for new users (many class names)
Easier for beginners due to ready-made UI

File Size
Smaller in production (with PurgeCSS)
Larger due to prebuilt components

Responsiveness
Built-in responsive utilities (e.g., md:)
Uses breakpoints within components

JavaScript Dependency
None (fully CSS-based)
Relies on JS for some components (e.g., modals)

Ecosystem/Plugins
Growing ecosystem, headless UI tools
Mature and widely used

Summary: Use Tailwind when it is necessary to maintain the full control in the custom design system and Bootstrap when it is desirable to develop a prototype quickly with pre-designed consistent elements.
