A simple flexbox-based grid system

JigSass Grid is a responsive Sass (SCSS) flexbox-based grid system, with a display: inline-block fallback backed in, where possible.

It is intended to be both flexible (pun intended) and easy to use. As part of the JigSass ecosystem, JigSass Grid integrates with its other modules, relying on some of them for consistent resposive breakpoints, sizing and more.


Using npm:

npm i -S jigsass-objects-grid


Availeable classes

For classes and modifiers (including responsive modifiers) to be generated in CSS output, they must be explicitly enabled in the configuration maps (see usage below).

Grid containers:

  • --start, --center, --end, --rev, --space-between, --space-around
  • --top, --middle, --bottom, --equal-height
  • --gutter-X (gutter width, See here).

Grid items:

  • --col, --center,
  • --top, --middle, --bottom, --equal-height
  • --gutter-X (gutter width, See here).
  • --gutter-gutter-rule-X (See here).
  • --X-of-Y
  • --offset-X-of-Y


First, import JigSass Grid into your main stylesheet:

@import 'path/to/jigsass-objects-grid/scss/index'

And optionally reconfigure the defaults to your liking.

To create a grid context, simply attach the .o-grid class to an element, Any element, which will serve as a grid container. You can now add grid items to it (with a class of .o-grid__item). Grid containers' only legitimate children are grid items, and those, in turn, may only reside within a grid container.

Like all other JigSass modules, JigSass Grid does not automatically generate any CSS output when imported. In order to use its classes, you would have to first explicitly indicate your intention to use them by enabling their generation in the associated configurations map, Leaving us only with CSS we need.

All JigSass Grid classes are responsive-enabled, using JigSass MQ and the breakpoints defined in the $jigsass-breakpoints variable.

Based on enabled selectors in the configuration map, responsive modifiers are generated according to the following logic:


So, assuming the medium, large and landscape breakpoints are defined in $jigsass-breakpoints as 600px, 1024px and (orientation: landscape) respectively,

$jigsass-grid-conf: (
  no-breakpoint: (
    no-modifier: true,
    end: true,
  until-medium: (
    end: true,
  from-large-when-landscape: (
    end: true,

will generate the following classes:

  • .o-grid, which is not limited to any media-query.
  • .o-grid--end, which is not limited to any media-query.
  • .o-grid--end--until-medium, which will be in effect at (max-width: 37.49em) and will override styles in the default class until that point.
  • .o-grid--end--from-large-when-landscape, which will go into effect at (min-width: 64em) and (orientation: landscape) and will override styles in the default class under these conditions.


The full documentation is available here.


It is a best practice for JigSass modules to not automatically generate css on @import, but rather have to user explicitly enable the generation of specific styles from the module.

Contributions in the form of pull-requests, issues, bug reports, etc. are welcome. Please feel free to fork, hack or modify JigSass Object Grid in any way you see fit.

Writing documentation

Good documentation is crucial for usability, scalability and maintainability. When contributing, please do make sure that both its Sass functionality (functions, mixins, variables and placeholder selectors), as well as the CSS it generates (selectors, concepts, usage exmples, etc.) are well documented.

Jigsass Grid uses Jonathan Neal's mdcss.

When styles and documentation comments are not automatically generated by your module on @import, please use the sgSrc/sg.scss file to enable their generation.

In addition, any file in sgSrc/assets will be available for use in the style guide.
