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 Spectre CSS ?

Spectre.css is a lightweight (~10 KB gzipped), responsive, and modern CSS framework crafted by Yan Zhu. It offers a solid foundation for building clean UIs with minimal overhead, utilizing Flexbox-based layouts, pure CSS components, and utility classes—all designed with elegance and efficiency in mind.

Key Features of Spectre CSS

  • Clean Design Language: Comes with thoughtfully designed elements and a consistent UI approach.
  • Pure CSS Components & Utilities: Includes buttons, forms, typography, icons, cards, toasts, modals, navbars, and more.
  • Experimentals for Advanced Features: CSS-only components like carousels, parallax scrolling, comparison sliders, calendars, and off-canvas menus.
  • Minimal Dependency on JavaScript: Leverages CSS pseudo-classes (:checked, :target, :hover) for interactivity, JavaScript can be added for enhanced behavior.

Advantages of Spectre CSS

  • Free and Open Source (MIT License): No cost, great for personal and commercial use.

Disadvantages of Spectre CSS

  • Limited Documentation for Experimentals: Advanced CSS-only components may require extra exploration and understanding.
  • CSS-Only Interactivity Has Limitations: Some interactive components may need JavaScript for full functionality.
  • IE10+ Support Only (and Partial): Some older browser features may not be fully supported.
  • Still Relatively Lightweight Ecosystem: Not as popular or widely used as Bootstrap, Tailwind, etc.

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,

Copy Code
1 2 3 <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

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.
