Vanilla Framework CSS

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 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.

What is Vanilla Framework CSS?

Vanilla Framework is an open-source, lightweight, and extensible CSS framework developed by Canonical (the creators of Ubuntu). It’s designed to provide a consistent and responsive design foundation without unnecessary bloat. Unlike component-heavy frameworks such as Bootstrap or Foundation, Vanilla focuses on clean base styles, responsive layouts, and utility classes that can be extended into full design systems.

It’s particularly popular for enterprise projects and design systems where consistency, accessibility, and scalability matter more than having hundreds of prebuilt UI widgets.

Key Features of Vanilla Framework

Key Features of Vanilla CSS
  • Lightweight & Scalable: Provides only what you need, no bloat.
  • Responsive Grid System: Built-in grid system for mobile-first design.
  • Accessibility First: Designed with WCAG compliance in mind.
  • Design Consistency: Used by Canonical across Ubuntu products.
  • Sass Support: Highly customizable via Sass variables and mixins.
  • Framework Agnostic: Works with plain HTML, React, Angular, Vue, or any setup.

Advantages of Vanilla CSS

  • Good Documentation: Clear guidelines with usage examples.
  • Clean and Lightweight: Minimal CSS, loads fast, and avoids bloat.
  • Consistent UI/UX: Ideal for creating unified design systems.
  • Enterprise-ready: Backed by Canonical, proven in large-scale projects.
  • Customizable with Sass: Change themes, colors, and spacing easily.
  • Accessibility Focused: WCAG-compliant components for inclusive design.

Disadvantages of Vanilla Framework

  • Less Popular in Freelance/Startup Space: Mainly adopted by enterprises like Canonical.
  • No Built-in JavaScript: Only CSS, you’ll need custom JS for interactivity.
  • Limited Community Support: Not as popular as Bootstrap or Tailwind.
  • Learning Curve with Sass: Beginners may find customization tricky.
  • Smaller Ecosystem: Fewer templates, themes, and third-party plugins.
