What sets Spartan apart?

Spartan will definitely convince you with its very unique grid creation API. While you define some variables in other grid systems which will then be used to create a predefined grid structure, Spartan provides you with a sensible set of mixins to freely customize your setup and get the most out of our grid system: you define how you want to use your grid!


  • supports all common grid features:
    • fluid or static grid cells width
    • independent gutter width, fluid or static
    • fully responsive
    • cell offsets
    • cell reordering
  • grid creation API for maximum flexibility
  • straight forward, easy to use
  • freely customizable css classes
  • tiny: 2.2KB of minified base css

LessCSS Support

Note that from version 6.0.0 on we will drop LessCSS support because of lacking demand and simpler maintenance.

For LessCSS Support you can use Spartan v5.1.0.

Getting Started

Have a Project at the Ready?

Spartan will not generate any CSS until you use the setup API.

Just want to fiddle around?

  • Download Spartan
  • Install NodeJS and run npm install in the project directory
  • Adjust the grid setup
  • Execute npm start

Grid Structure

Here's a short example of Spartans base structure in a 12-cell grid:

<div class="g-container">
	<div class="g-cell g-span-3"></div>
	<div class="g-cell g-span-3"></div>
	<div class="g-cell g-span-3"></div>
	<div class="g-cell g-span-3"></div>
  • .g-container initializes a grid container with negative left margin (gutter) and uses H5BP clearfix to contain the floating .g-cells.
  • .g-cell applies default cell styles like float and padding (gutter).
  • .g-span-<cells> applies a cell based width relative to the set maximum amount of cells.

Basic Usage

Grid Setup

There are two ways to set up a grid with Spartan, within the basic usage we only explain the simpler one. If you need more flexibility, to set up viewport dependent grids etc. go to the advanced usage section.

The basic grid setup requires you to call just one mixin, pass in a configuration and an optional namespace; read more about custom classes in the documentation.

@import 'dist/spartan';

@include grid-bundle(<grid-width>, <gutter-width>, <grid-cells>, [grid-namespace]);

Example Setup

The following will implement a fluid grid with a fixed gutter of 20 pixels and 12 cells:

@include grid-bundle(100%, 20px, 12);

Config Types

There are actually 4 different ways to pass in your configuration:


@include grid-bundle(100%, 20px, 12);

Named Parameters

@include grid-bundle($width: 100%, $gutter: 20px, $cells: 12);


$grid-config: 100%, 20px, 12;

@include grid-bundle($grid-config);


$grid-config: (
    width: 100%,
    gutter: 20px,
    cells: 12

@include grid-bundle($grid-config);

In the case of named parameters and a config map you could even omit settings you don't need to change and rely on the grid's defaults, i.e. (width: 100%, gutter: 0, cells: 12).

Grid and Gutter Types

The grid and gutter type depend solely on the unit of the value you have given. If you define your grid width as 100% the grid will naturally use fluid percentage values, while it will use fixed pixel values if you define it as e.g. 940px. This counts for the gutter as well since grid and gutter types can be defined completely independently.

You can easily calculate a relative percentage gutter from other values with a built-in function: percentage(20px / 940px).

Grid Classes and Mixins

Spartan generates grid classes according to your configuration, but instead of applying these classes you can also use corresponding mixins to apply the grid in your css.




@include grid-span(<cells>)
@include grid-offset(<cells>)
@include grid-push(<cells>)
@include grid-pull(<cells>)


Override the width of a cell (default is full-width), equivalent to .g-span-{cells}.

The mixin allows you to pass in floating point numbers, which enables you to define literally any width.

Following an example of a 5 cell width in a 12 cell grid:


.g-cell-fifth {
	@include grid-span(12/5);


Indent a cell by the defined amount of grid cells, equivalent to .g-offset-{cells}. While there are just positive indents in generated classes, you could also call this mixin with negative values.

grid-push and grid-pull

You can reorder cells visually without changing the order in HTML with these mixins. Equivalent to .g-push-{cells} and .g-pull-{cells}, similar behavior as .grid-offset().


You can alternatively use the mixin grid-reorder() and pass in any number. If the passed number is positive or zero, it will simply call grid-push() and if the number is negative grid-pull() instead.

Advanced Usage

There's a detailed documentation about every aspect of Spartan with different approaches to setting up your most flexible grid.
