Bootstrap provides pre-designed components/classes while Tailwind CSS provides lots of low-level utility classes gives you more flexibility.
Tailwind CSS is often considered more “advanced” than Bootstrap, but let me explain why in simple terms.

While Bootstrap provides pre-designed components (like buttons, modals, navigation bars, etc.) that you can directly use, Tailwind CSS takes a different approach by giving you a set of low-level utility classes that you combine to build your design from scratch. It gives you more flexibility and allows you to style things the way you want, instead of relying on predefined styles.
Key Differences: Tailwind vs. Bootstrap
1. Customizability
- Bootstrap comes with pre-built components that are styled in a particular way (e.g., buttons, cards, modals, etc.). If you want to customize those components, you have to overwrite existing styles or use custom CSS, which can sometimes lead to messy or inconsistent results.
- Tailwind CSS, on the other hand, gives you utility classes for things like padding, margins, colors, borders, fonts, etc., and lets you build your design directly without worrying about overriding pre-styled components. You can tweak everything using Tailwind’s utility classes.
Example:
- In Bootstrap, you’d have to customize a button’s style by adding extra CSS classes or overwriting defaults:
<button class="btn btn-primary custom-btn">Click Me</button> - With Tailwind, you can apply utilities directly:
<button class="px-4 py-2 bg-blue-500 text-white rounded-lg">Click Me</button>
2. No Pre-built Components
- Bootstrap gives you pre-styled components that you just plug into your page, which is nice for fast development. But this can also limit how much you can customize those components unless you override styles.
- Tailwind doesn’t force any pre-designed components on you. Instead, it provides low-level utility classes so you have total control over your design. This means you can create any component you want from scratch without worrying about how it will look.
Example:
- With Bootstrap, to create a simple card, you would use pre-designed classes:
<div class="card"> <img class="card-img-top" src="..." alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">Some quick example text...</p> </div> </div> - With Tailwind, you’re free to design it however you want:
<div class="bg-white p-6 rounded-lg shadow-lg"> <img src="..." class="rounded-t-lg w-full" alt="..."> <h2 class="text-xl font-bold mt-4">Card title</h2> <p class="text-gray-600 mt-2">Some quick example text...</p> </div>
3. Smaller File Size (If You Customize Properly)
- Bootstrap includes a lot of unused styles because it has many pre-built components. If you don’t use all of them, it can increase your project’s file size.
- Tailwind can be much smaller if you configure it properly. It includes only the utilities you use in your project. Tailwind’s purge feature removes unused CSS, keeping the file size small.
Example:
- With Tailwind, if you use only a few utilities, your final CSS file will only include those utilities.
- Bootstrap includes a lot of unused CSS (like for components you’re not using), making the file size bigger.
4. Responsiveness (Mobile-First)
- Bootstrap provides responsive components (like grids, carousels, etc.), but you still have to deal with predefined breakpoints and media queries.
- Tailwind is mobile-first and uses a system of responsive utility classes. You can easily adjust styles based on different screen sizes by just adding a simple class like
md:,lg:, etc.
Example:
- In Bootstrap, you need to manage responsive design with predefined grid systems:
<div class="col-md-4 col-sm-12">Content</div> - In Tailwind, you can add responsive classes like this:
<div class="w-full md:w-1/3">Content</div>This means the element will take full width on small screens and one-third width on medium screens.
5. Learning Curve (It’s Different)
- Bootstrap is easy to get started with because of its pre-made components and a simple grid system. If you’ve worked with it before, you can quickly build websites by just sticking to the Bootstrap components.
- Tailwind has a different approach because you’re dealing with utility classes and combining them to create components. It may have a steeper learning curve, but once you get the hang of it, you’ll have complete flexibility and can create exactly what you want, with no restrictions.
Summary of Advantages of Tailwind Over Bootstrap
| Feature | Tailwind CSS | Bootstrap |
|---|---|---|
| Customization | Highly customizable, design from scratch with utility classes | Predefined components with limited customization |
| File Size | Smaller (with purge feature) | Larger (includes unused components) |
| Responsiveness | Mobile-first, flexible responsive classes | Predefined grid system and breakpoints |
| Components | Build components from scratch | Ready-made components with predefined styles |
| Learning Curve | Steeper (but more flexible once learned) | Easier to start, limited flexibility |
Conclusion
Tailwind CSS is not necessarily “better” than Bootstrap, but it offers more flexibility and customization. If you like building your designs from the ground up and want full control over how everything looks, Tailwind is a great choice. It gives you all the utilities to design everything yourself without being limited by pre-built components.
However, if you want to quickly put together a project with pre-made, responsive components, then Bootstrap is a great option to speed up development.
