A 12 column responsive, flexbox-based grid system for laying out documents, templates and components.
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 data-o-grid-colspan="one-half Ltwo-thirds"></div>
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.
