Pure
====

[](#pure)

[![Pure](https://cloud.githubusercontent.com/assets/449779/5291099/1b554cca-7b03-11e4-9157-53a12d91b34a.png)](http://purecss.io/)

A set of small, responsive CSS modules that you can use in every web project. [https://purecss.io/](http://purecss.io/)

[![Build Status](https://github.com/pure-css/pure/actions/workflows/test.yml/badge.svg)](https://github.com/pure-css/pure/actions/workflows/test.yml/badge.svg)

Features
--------

[](#features)

Pure is 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](http://necolas.github.io/normalize.css/) to fix cross-browser compatibility issues.
- Consistently styled buttons that work with `` and `` 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.
- Extremely small file size: **3.7KB minified + gzip**.

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

[](#get-started)

Check out the [Get Started](https://purecss.io/start/) page for more information.

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

[](#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](http://gruntjs.com/) to build Pure.

```
git clone git@github.com:pure-css/pure.git
cd pure
npm install
grunt
```

### Build Files

[](#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, usually 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.css`: A rollup of all `[module].css` files in the `build/` dir. This is a responsive roll-up of everything, non-minified. Note: does not contain responsive grids with @media queries.
- `pure-min.css`: Minified version of `pure.css` that should be used in production.
- `pure-nr.css`: A Rollup of all modules without @media queries. This is a non-responsive roll-up of everything, non-minified.
- `pure-nr-min.css`: Minified version of `pure-nr.css` that should be used in production.
- `grids-responsive.css`: Unminified version of Pure's grid stylesheet which includes @media queries.
- `grids-responsive-min.css`: Minified version of `grids-responsive.css` that should be used in production.
