spaceBase is a Sass-based responsive CSS framework.

Many CSS frameworks are meant to be included and left alone. But spaceBase is a boilerplate layer that can be built upon and tailored for your needs. It combines best practices for today’s responsive web with the core components we use on every project. Consider it the launch pad for your adventures into cyberspace.

spaceBase is the front-end starter files for any new web project. It sets up your Sass architecture and normalizes your CSS and native HTML elements. It provides the structural groundwork for your application.

Getting Started

  1. $ npm install spacebase or download the ZIP and copy its contents into your project folder.
  2. Use your favorite Sass 3.3 compiler to watch for changes and compile the files. (Setting up Sass is outside the scope of this document.)
  3. Open scss/_vars.scss to make changes to your global variables.
  4. Start building out your HTML. We've included index.html as a starting point.
  5. scss/base/ is the core of spaceBase. Build your UI layer in scss/ui/

Your editor can be setup with EditorConfig so that code style standards are enforced automatically. See http://editorconfig.org/#download and install the plugin for your editor of choice.
