Getting started

Install with Bower:

bower install less-grid-system

or NPM:

npm install less-grid-system

or download the source code from GitHub.

Basic usage

LESS grid system does not clutter your markup with unnecessary classes.

You write column declarations directly in your stylesheet.

Configuring variables

Default configuration will create a 12-column 1180px grid.

You can change the number, size and gutter of columns and adjust the breakpoint for the grid, by changing the variables in the grid.less file.

// Defaults
@gridBreakpoint:	480px;
@gridColumnCount:	12;
@gridGutter:		20;
@gridColumn:		80;

Creating columns

To create a column, call the column mixin:

#grid > .column( [ number of columns: 1 ], [ responsive: true ], [ auto clear margins: true ] )

All arguments are optional.

You don't need to worry about things like first or last classes - the mixin will only add gutters where necessary.

If you want to disable this behavior, you can pass an optional @autoClearMargins: false to the mixin.

By default, all columns are responsive, and will drop down on smaller screens, stacking on top of each other. You can disable this feature by setting the @responsive argument to false when calling the mixin.

Pushing & pulling

You can either push:

#grid > .push( [ number of columns to push by ] );

or pull a column:

#grid > .pull( [ number of columns to pull by ] );

Advanced usage

LESS grid system was designed with flexibility in mind, so you can customize it however you want.

Changing grid settings on the fly

You can either alter global variables or alternatively you can change them on the fly by creating a new instance of the grid mixin.

This is useful, when you want to use more than one version of the grid on one website.

You can define a new instance of the grid by calling the core mixin with new parameters:

// Define grid instances
#grid16 { #dynamicGrid( 16, 55, 20 ); }
#grid24 { #dynamicGrid( 24, 30, 20 ); }

Syntax is as follows:

#[ reference name ] { #dynamicGrid( [ number of columns ], [ column width ], [ gutter size ] ) }

Then you can use it in your stylesheet by simply calling the reference:

.my-grid-16 {

	#grid16 > .container;

	.column { #grid16 > .column; }

}

.other-grid-24 {

	#grid24 > .container;

	.column { #grid24 > .column; }

}

Fluid grid

By default, all grids have a fixed width defined by the wrapping container - but you can make them fluid by setting the container width to auto or 100%.

The following snippet will create a fluid grid, with column sizes proportional to the fixed grid.

.container {

	width: auto;

	.column { grid > .column( 3 ); }

}

.container {

	width: 75%;

	.column { grid > .column( 3 ); }

}

Nested grids

If you want to create a column containing nested columns inside it, switch to:

#grid > .columnOuter;

instead of:

#grid > .column;

You will also need to wrap inner columns in a new element, giving it the .row class.

Examples

• Default [ source ]
• Custom (16 columns) [ source ]
• Custom (24 columns) [ source ]
• Fluid [ source ]
• Four columns [ source ]
• Pull [ source ]
• Push [ source ]
• Sidebar [ source ]
• Double sidebar [ source ]
• One level nested [ source ]
• Two levels nested [ source ]

The idea behind LESS grid system was hugely inspired by Twitter Bootstrap and The Semantic Grid System.
