Package Exports

postcss-neat

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (postcss-neat) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

PostCSS-Neat

A semantic and fluid grid framework on top of PostCSS

PostCSS-Neat is a fluid grid framework built with the aim of being easy enough to use out of the box and flexible enough to customize down the road.

Using PostCSS-Neat

Usage:

postcss([
  require('postcss-neat')(/* { options } */)
])

There is a gulp usage:

var gulp = require('gulp');
gulp
  .task('css', function () {
    var processors = [
      require('autoprefixer-core')({ browsers: ['last 1 version'] }),
      require('postcss-neat')(/* { options } */)
    ];
    return gulp.src('./input/*.css')
      .pipe(require('gulp-postcss')(processors))
      .pipe(gulp.dest('./output/'));
  })
  .task('default', ['css']);

See the demo page for a full list of features.

Let's walk through a simple example. Include the outer-container at-rule in the topmost container (to which the max-width setting will be applied):

.container {
  @neat-outer-container;
}

Then use span-columns on any element to specify the number of columns it should span:

.element {
  @neat-span-columns 6;
}

If the element's parent isn't the top-most container, you need to add the number of columns of the parent element to keep the right proportions:

.container {
  @neat-outer-container;

  .parent-element {
    @neat-span-columns 8;

    .element {
      @neat-span-columns 6 8;
    }
  }
}

To make your layout responsive, use the postcss-media-minmax media queries functionality to modify both the grid and the layout:

.container {
  @neat-span-columns 4;

  @media (width >= 768px) {
    @neat-span-columns 2;
  }
}

To help debug your layouts there is a show-grid at-rule, note that it should be used in conjunction with outer-container:

.container {
  @neat-outer-container;
  @neat-show-grid; /* defaults to 1 12 */
}

The result you get by using show-grid at-rule is shown below: @neat-show-grid

The third parameter of show-grid at-rule controls the location of where the grid will be applied to. The allowed values are before, after (default value) or background:

.container {
  @neat-outer-container;
  @neat-show-grid 4 12 background;
}

Custom settings

If you are planning to override the default grid settings (12 columns, and etc.), set variables you want to override in options that you pass to PostCSS-neat call:

postcss([
  require('postcss-neat')({
    neatMaxWidth: '128em'
  })
])

There is a list of all available variables:

neatDefaultDisplay, sets the default display mode. Can be block, table or block-collapse. Default is block.
neatDefaultDirection, sets the default layout direction of the grid. Can be LTR or RTL. Default is LTR.
neatGridColumns, sets the total number of columns in the grid. Default is 12.
neatColumnWidth, sets the relative width of a single grid column. Default is 4.235801032000001em.
neatGutterWidth, sets the relative width of a single grid gutter. Default is 1.618em.
neatMaxWidth, sets the max-width property of the element that includes outer-container. Default is 64em.
debugGridColor, sets the background color for the debugging grid. Default is #ecf0f1.
debugGridLocation, sets the default location of the debugging grid. Default is after.
