A 12 column responsive, flexbox-based grid system for laying out documents, templates and components.
This component is a collection of Sass styles to build a 12 column grid system, with a few JavaScript helpers.
Using the Origami Build Service:
<head>
…
<link rel="stylesheet"
href="https://origami-build.ft.com/v2/bundles/css?modules=o-grid@^4.0.0" />
</head>
Or, to install it manually:
bower install o-grid --save
// your-app/main.scss
$o-grid-is-silent: false;
@import 'o-grid/main';
// your-app/main.js
// Return the current layout (e.g. default, S, M, L, XL)
import oGrid from 'o-grid';
let currentLayout = oGrid.getCurrentLayout();
console.log(currentLayout);
// Return the current gutter (e.g. 10px, 20px)
import oGrid from 'o-grid';
let currentGutter = oGrid.getCurrentGutter();
console.log(currentGutter);
<div class="o-grid-container">
<div class="o-grid-row">
<!-- two divs, spanning a total of 12 columns -->
<div data-o-grid-colspan="8">A div, 8 columns wide</div>
<div data-o-grid-colspan="4">Another div, 4 columns wide</div>
</div>
</div>
Set a number of columns per layout:
<div class="o-grid-container">
<div class="o-grid-row">
<div data-o-grid-colspan="6 L8" class="first-column">
Half by default, then 8 columns wide on Large layout and up
</div>
<div data-o-grid-colspan="6 L4" class="second-column">
Half by default, then 4 columns wide on Large layout and up
</div>
</div>
</div>
div {
@include oGridContainer();
> div {
@include oGridRow();
}
}
.first-column {
// Half by default, then 8 columns wide on Large layout and up
@include oGridColspan((default: 6, L: 8));
}
.second-column {
// Half by default, then 4 columns wide on Large layout and up
@include oGridColspan((default: 6, L: 4));
}

div { @include oGridColspan((default: one-half, L: two-thirds)); }
A full width column for all sizes except large screens and up, where it spans on 9 columns:
<div data-o-grid-colspan="full-width L9"></div>
div { @include oGridColspan((default: full-width, L: 9)); }
A half width column that becomes full-width on medium screens and up:
<div data-o-grid-colspan="one-half M12"></div>
div { @include oGridColspan((default: one-half, M: 12)); }
A column which gradually takes up a greater portion of horizontal space as the screen gets smaller:
<div data-o-grid-colspan="4 M3 L2 XL1"></div>
div { @include oGridColspan((default: 4, M: 3, L: 2, XL: 1)); }
A column which has width: auto on small screens, and then takes half the available space on medium screens and up:
<div data-o-grid-colspan="M6"></div>
div { @include oGridColspan((M: 6)); }
To include all styles call the oGrid mixin.
@include oGrid();
o-grid css may be included granularly by passing options to the oGrid mixin.
@include oGrid($opts: (
'bleed': true, // The container modifier `o-grid-container--bleed`
'shuffle-selectors': true, // offset, push, and pull selectors such as `push4`
'friendly-selectors': true, // Human friendly selectors such as `data-o-grid-colspan="one-half"`
'surface': ('current-layout', 'layout-sizes'), // Styles to surface o-grid layout to JavaScript features
'rows': ('compact') // The row modifier `o-grid-row--compact`
));
hide the column, show it again at Large (L) layout size, and hide it at the largest (XL) layout size:
<div data-o-grid-colspan="hide L12 XLhide"></div>
div { @include oGridColspan((default: hide, L: 12, XL: hide)); }
center the column and uncenter it at Large (L) layout size:
<div data-o-grid-colspan="center Luncenter"></div>
.my-column {
@include oGridCenter;
@include oGridRespondTo(L) {
@include oGridUncenter;
}
}
<div data-o-grid-colspan="8 push4"></div>
<div data-o-grid-colspan="4 pull8"></div>
// Content is first in the source
.content {
@include oGridColspan(8);
@include oGridPush(4); // outputs left: -33.333333333%;
}
// Sidebar comes second in the source but appears first on the left
.sidebar {
@include oGridColspan(4);
@include oGridPull(8); // outputs right: -66.666666667%;
}
Responsively:
<div data-o-grid-colspan="L8 Lpush4"></div>
<div data-o-grid-colspan="L4 Lpull8"></div>
// Content is first in the source
.content {
@include oGridColspan((L: 8));
@include oGridRespondTo(L) {
@include oGridPush(4); // outputs left: -33.333333333%;
}
}
// Sidebar comes second in the source but appears first on the left
.sidebar {
@include oGridColspan((L: 4));
@include oGridRespondTo(L) {
@include oGridPull(8); // outputs right: -66.666666667%;
}
}
<div data-o-grid-colspan="8 offset4"></div>
<div data-o-grid-colspan="L8 Loffset4"></div>
div {
@include oGridColspan(8);
@include oGridOffset(4); // outputs margin-left: 33.333333333%;
}
div {
@include oGridColspan((L: 8));
@include oGridRespondTo(L) {
@include oGridOffset(4); // outputs margin-left: 33.333333333%;
}
}
The container size can snap between fixed-widths as the viewport gets larger:
<!-- Make the whole document snappy -->
<body class="o-grid-snappy">
<div class="o-grid-container">
<div class="o-grid-row">
…
</div>
</div>
</body>
<!-- Make a container snappy -->
<div class="o-grid-container o-grid-container--snappy">
<div class="o-grid-row">
…
</div>
</div>
To remove gutters from in between columns in a row, use the o-grid-row--compact class or the oGridRowCompact() mixin:
<div class="o-grid-row o-grid-row--compact">
<div data-o-grid-colspan="6">Look 'ma, no gutters</div>
<div data-o-grid-colspan="6">Look 'pa, no gutters here either</div>
</div>
div {
@include oGridContainer();
> div {
@include oGridRow();
@include oGridRowCompact('.column');
}
.column {
@include oGridColspan((default: full-width, S: 3));
}
}
To remove gutters from the left and right sides of the grid container, use the o-grid-container--bleed class. Note that it is not possible to remove the outer gutters for an individual row, instead you need to start a new container.
<div class="o-grid-container o-grid-container--bleed">
<div class="o-grid-row o-grid-row--compact">
<div data-o-grid-colspan="6">Look 'ma, no gutters</div>
<div data-o-grid-colspan="6">Look 'pa, no gutters here either</div>
</div>
</div>
For simplicity, examples below don't show the output code that brings support for Internet Explorer.
el { @include oGridColspan(); }
Outputs:
// Fallbacks for Internet Explorer omitted in this example
el {
position: relative;
float: left;
box-sizing: border-box;
flex: 1 1 0%;
padding-left: 10px;
}
@media (min-width: 46.25em) {
el {
padding-left: 20px;
}
}
el { @include oGridColspan($span: 4); }
Outputs:
el {
position: relative;
float: left;
box-sizing: border-box;
flex: 1 1 0%;
padding-left: 10px;
display: block;
flex-basis: 33.33333%;
min-width: 33.33333%;
max-width: 33.33333%;
width: 33.33333%;
}
@media (min-width: 46.25em) {
el {
padding-left: 20px;
}
}
el {
@include oGridColspan((
default: full-width,
M: 6
));
}
Outputs:
el {
position: relative;
float: left;
box-sizing: border-box;
flex: 1 1 0%;
padding-left: 10px;
display: block;
flex-basis: 100%;
min-width: 100%;
max-width: 100%;
width: 100%;
}
@media (min-width: 46.25em) {
el {
display: block;
flex-basis: 50%;
min-width: 50%;
max-width: 50%;
padding-left: 20px;
}
}
@include oGridRespondTo($from, $until) {
// Styles
}
To create styles that respond to the same breakpoints as the grid, this Sass mixin can be used to wrap the styles in the appropriate media query. It should be passed S, M, L or XL depending on which layout size the style should apply to e.g.
@include oGridRespondTo(S) {
.o-example-module .item-subheading {
font-size: 0.5em;
}
}
.o-example-module .item-subheading {
@include oGridRespondTo(XL) {
color: red;
}
}
.o-example-module .item-subheading {
@include oGridRespondTo($until: L) {
width: auto;
}
}
It relies on Sass MQ to output mobile-first @media queries.
$from is inclusive but $until is exclusive – e.g. @include oGridRespondTo(S, L) matches the breakpoints S and M, but not L.
el {
margin-left: oGridGutter();
@include oGridRespondTo(L) {
margin-left: oGridGutter(L);
}
}
Outputs:
el {
margin-left: 10px;
}
@media (min-width: 61.25em) {
el {
margin-left: 20px;
}
}
.un-rowify {
@include oGridResetRow;
}
.de-columnify {
@include oGridResetColumn;
}
Some of the variables used by the grid (see _variables.scss) can be used to customise the grid system.
Here are the most useful ones:
// Switch Silent mode off
$o-grid-is-silent: false;
// Show the currently active breakpoint and output loaded settings
$o-grid-debug-mode: true;
// Gutters (distance between 2 columns), in pixels
$o-grid-gutters: (default: 10px, M: 20px);
// Grid mode
// - fluid: full width up to the largest layout's width
// - snappy: fluid width until the layout defined in $o-grid-start-snappy-mode-at (default: M),
// and then snaps into a larger fixed layout at each breakpoint
// (used by Next FT)
// - fixed: always fixed-width with the layout defined by
// $o-grid-fixed-layout (default: L)
$o-grid-mode: fluid (default) | snappy | fixed;
// Default layouts
$o-grid-layouts: (
S: 490px,
M: 740px,
L: 980px,
XL: 1220px,
);
Products who need to add other breakpoints/layouts should use the helper oGridAddLayout():
@import 'o-grid/main';
// Add various layouts
@include oGridAddLayout(
$layout-name: XS,
$layout-width: 360px
);
@include oGridAddLayout(
$layout-name: P,
$layout-width: 600px,
$gutter-width: 24px
);
// Layouts are now:
// XS: 360px,
// S: 490px,
// P: 600px,
// M: 740px,
// L: 980px,
// XL: 1220px
// Include all o-grid styles, including:
// - Surface the layout currently displayed to make it readable in JS
// - Generate grid helpers classes and data attributes.
@include oGrid();
Enable debug mode to see the currently active breakpoint in the top-right corner of the page (based on sass-mq's show-breakpoints feature).
$o-grid-debug-mode: true;
getCurrentLayout()Returns the name of the layout currently displayed.
import oGrid from 'o-grid';
console.log(oGrid.getCurrentLayout());
// > default | S | M | L | XL
getCurrentGutter()Returns the width of the gutter currently displayed.
import oGrid from 'o-grid';
console.log(oGrid.getCurrentGutter());
// > 10px | 20px
If using Sass, ensure the surface option includes current-layout so JavaScript can retrieve layout information from our CSS.
getGridBreakpoints()Returns the sizes of all grid breakpoints available.
import oGrid from 'o-grid';
console.log(oGrid.getGridBreakpoints());
// > { "layouts": { "S": "490px", "M": "740px", "L": "980px", "XL": "1220px" } }
If using Sass, ensure the surface option includes layout-sizes so JavaScript can retrieve layout information from our CSS.
enableLayoutChangeEvents()Enable matchMedia queries that fire an o-grid.layoutChange event upon layout change.
import oGrid from 'o-grid';
oGrid.enableLayoutChangeEvents();
If using Sass, ensure the surface option includes layout-sizes so JavaScript can retrieve layout information from our CSS.
