Vanilla – extensible CSS framework

Last Updated on March 8, 2026

Vanilla Framework is an extensible CSS framework, built using Sass and is designed to be used either directly or by using themes to extend or supplement its patterns.

This is free and open source software.

Key Features

  • Multiple ways to display code using the standard HTML elements: Inline, Block, Code snippet, Code snippet with icon, Numbered code snippet, and Dropdowns.
  • Uses Normalize to reset default browser styling on page elements. This helps remove any quirks or nuances specific to certain browsers before further styling is layered on top.
  • Supports client-side theming based on CSS properties (instead of previously used build-time SCSS based theming). Themes supported:
    • light (default, or provided by is-light class).
    • paper (provided by is-paper class, recommended for websites) which extents the light theme, but uses a light grey background.
    • dark (provided by is-dark class).
  • Patterns.
