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: **4.3KB minified + gzip**.

Get Started
-----------

To get started using Pure, go to the [Pure CSS website][Pure]. 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:

```html
<link rel="stylesheet" href="http://yui.yahooapis.com/pure/0.2.1/pure-min.css">
```


Build From Source
-----------------

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

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

### Build Files

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]-core.css`: The minimal set of styles, ususally structural, that
  provide the base on which the rest of the module's styles build.

* `[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.
