A set of small, responsive CSS modules that you can use in every web project.

Build Status Gitter

This project is looking for maintainers to support and enhance Pure.css. If you are interested please leave a comment in the Github issue.


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

  • 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

Check out the Get Started page for more information.

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.

$ git clone [email protected]:pure-css/pure.git
$ cd pure
$ npm install
$ grunt

Build Files

Now, all Pure CSS files should be built into the

directory. All files that are in this build directory are also available on the CDN. The naming conventions of the files in the
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
    from the
    dir. This is the non-responsive version of a module.
  • [module].css
    : Rollup of
    from the
    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
    files in the
    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
    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
    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
    that should be used in production.
