Features

Pure is meant to be a starting point for every website or web app. We take care of all the CSS work that every site needs, without making it look cookie-cutter:

• A responsive grid that can be customized to your needs.

• A solid base built on Normalize.css to fix cross-browser compatibility issues.

• Consistently styled buttons that work with <a> and <button> elements.

• Styles for vertical and horizontal menus, including support for dropdown menus.

• Useful form alignments that look great on all screen sizes.

• Various common table styles.

• An extremely minimalist look that is super-easy to customize.

• Responsive by default, with a non-responsive option.

• Easy one-click customization with the Skin Builder.

• Extremely small file size: 4.8KB minified + gzip.

Get Started

To get started using Pure, go to the Pure CSS website. The website has extensive documentation and examples necessary to get you started using Pure.

You can include the Pure CSS file in your project by fetching it from Yahoo's CDN:

<link rel="stylesheet" href="http://yui.yahooapis.com/pure/0.1.0/pure-min.css">

Build From Source

Optionally, you can build Pure from its source on Github. To do this, you'll need to have NodeJS and npm installed. We use Grunt to build Pure.

$ git clone git@github.com:yui/pure.git
$ cd pure
$ npm install
$ grunt

Now, all Pure CSS files should be built into the pure/build/ directory. All files that are in this build directory are also available on the CDN. The naming conventions of the files in the build/ directory follow these rules:

• [module]-nr.css: Rollup of [module]-core.css + [module].css + [module]-[feature].css from the src/[module]/ dir. This is the non-responsive version of a module.

• [module].css: Rollup of [module]-nr.css + [module]-r.css from the build/ dir. This is the responsive version of a module.

• *-min.css: A minified file version of the files of the same name.

• pure-min.css: A rollup of all [module]-min.css files in the build/ dir. This is a responsive roll-up of everything.

• pure-nr-min.css: A Rollup of all modules without @media queries. This is a non-responsive roll-up of everything.

Note: To save your fingers from The Developer Konami Code: ⌘⇥ ⌃C ↑ ⏎ use the grunt watch task:
