Tailwind CSS vs Bootstrap vs Custom CSS: Which One Should You Choose in 2026?

Introduction

Choosing the right CSS approach is one of the most important decisions in modern web development. Developers today usually pick one of these three options:

• Tailwind CSS
• Bootstrap
• Custom CSS

Each approach has its own strengths, weaknesses, and ideal use cases. In this blog, we will compare Tailwind CSS vs Bootstrap vs Custom CSS in a practical, beginner-friendly way so you can confidently decide what to use for your next project.

What is Tailwind CSS?

Tailwind CSS is a utility-first CSS framework that allows developers to style elements using predefined utility classes directly in HTML.

Instead of writing custom CSS, you compose designs using small utility classes such as spacing, colors, typography, and layout helpers.

Example

<button class="bg-blue-500 text-white px-4 py-2 rounded">
  Save
</button>

What is Bootstrap?

Bootstrap is a component-based CSS framework that provides ready-made UI components like buttons, cards, modals, forms, and grids.

It is beginner-friendly and helps build layouts quickly using predefined classes.

Example

<button class="btn btn-primary">
  Save
</button>

What is Custom CSS?

Custom CSS means writing your own CSS from scratch without relying on any framework. This gives full control over styling but requires more effort, planning, and maintenance.

Example

<button class="save-btn">
  Save
</button>

.save-btn {
  background-color: #2563eb;
  color: white;
  padding: 8px 16px;
  border-radius: 6px;
}
