Foundation
Tachyons
You know how building a website can feel like a lot, especially when you’re trying to style every little thing yourself? Buttons, forms, layouts… it adds up fast. That’s where UI frameworks really save the day. They give you a bunch of premade design elements that you can just drop in and go. It’s like having a design starter pack that helps your site look clean and professional, without spending forever tweaking the details.
What is Foundation?
Foundation by Zurb is a responsive front-end framework designed for creating responsive and accessible websites quickly. It is known for its mobile-first approach and powerful grid system, Foundation provides a set of prebuilt components and tools that help developers create professional websites, prototypes, and production-ready apps.

What isTachyons?
Tachyons is a functional/atomic CSS framework that uses small, reusable utility classes. Instead of big UI components or deeply nested CSS, Tachyons encourages developers to style elements using many tiny, single-purpose classes.
Let's check by the example,

<button class="f6 link dim br3 ph3 pv2 mb2 dib white bg-dark-blue">
Click Me!
</button>Here, each class f6, br3, ph3 controls a specific CSS property like font size, border radius, padding, etc. This modular approach makes styling predictable and reusable.
Tachyons was one of the innovator of the utility-first CSS movement—it influenced modern frameworks like Tailwind.
Key Features of Tachyons
- Atomic CSS Classes: Every class does one thing (e.g., pa3 = padding).
- Responsive Utilities: Classes adapt to multiple screen sizes.
- Small Bundle Size: Around 14KB minified & gzipped.
- Performance-Oriented: Encourages minimal CSS output.
- Accessible Defaults: Typography and spacing built for readability.
- Framework-Free: Works with plain HTML, React, Vue, or any frontend.
- Rapid Prototyping: Compose UIs quickly with utility classes.
Advantages of Tachyons
- Stable: Mature and widely battle-tested since 2015.
- Highly Composable: Mix classes freely to achieve complex designs.
- Consistent: Predictable, reusable naming system.
- Fast & Lightweight: Tiny CSS footprint.
- Great for Prototypes: Quickly test ideas without writing custom CSS.
- Utility-First Approach: No deep CSS overrides needed.
Disadvantages of Tachyons
- Smaller Community: Fewer themes, templates, and ecosystem resources.
- Messy HTML: Can lead to class-heavy markup that’s harder to read.
- No Components: You must build everything (buttons, navbars, modals) manually.
- Learning Curve: Class names (pa3, f5) are shorthand and non-intuitive for beginners.
- Not Actively Maintained: Less frequent updates compared to newer frameworks.
