Grid helpers to enable easy cross browser grids. The grids use absolute widths in older versions of IE or percentage based widths in modern browsers.
%site-width-containercreates a 960px wide elastic container for you site content block%grid-rowcontainer for a row of columns@mixin grid-column($width, $full-width: tablet)a mixin to create grid columns of fraction width
These three grid helpers are designed to be used together and aren't guaranteed to work or behave in a predictable way if used in isolation.
There is also an %outdent-to-full-width selector which can be extended to
outdent and element and cause it to take up the edge gutters and butt up to the
edge of smaller screens.
#page-container {
@extend %site-width-container;
}
.grid-row {
@extend %grid-row;
.column-third {
@include grid-column( 1/3 );
}
.column-two-thirds {
@include grid-column( 2/3 );
}
}
.hero-image {
@extend %outdent-to-full-width;
}
<div id="page-container">
<div class="grid-row">

Media query and IE helpers. These make producing responsive layouts and attaching IE specific styles to elements really easy.
To use the IE conditionals you will need to add extra stylesheets for each IE which look like:
// BASE STYLESHEET FOR IE 6 COMPILER
$is-ie: true;
$ie-version: 6;
@import "application.scss";
Where application.scss is the name of your base stylesheet.
@mixin media($size: false, $max-width: false, $min-width: false)
note: the parameters are mutually exclusive and the first one found will be used.
$size
size can be one of desktop, tablet, mobile. desktop and tablet
should be used to add styles to a mobile first stylesheet. mobile should be
used to add styles to a desktop first stylesheet.
It is recommended that you primarily use desktop for new stylesheets to
enhance mobile first when serving to mobile devices.
$min-width
$max-width
These should be set to an absolute pixel value. They will get added directly to their respective @media queries.
$ignore-for-ie
Styles that would normally be wrapped in @media queries by this mixin will be instead
added to the main block if the $is-ie variable is true.
Setting $ignore-for-ie to true means those styles will not be added.
div.columns {
border: 1px solid;
@include media(desktop){
width: 30%;
float: left;
}
@include media($min-width: 500px){
width: 25%;
}
@include media($max-width: 400px){
width: 25%;
}
}
Conditially send CSS to IE browsers less than or equal to the named version.
@include ie-lte($version)
$version
version is an integer value. Possible values are 6, 7, 8.
div.columns {
border: 1px solid;
@include ie-lte(7){
border: 0;
}
}
Send CSS to a named IE version.
@include ie($version)
$version
version is an integer value. Possible values are 6, 7, 8.
div.columns {
border: 1px solid;
@include ie(6){
border: 0;
}
}

A collection of font-mixins. There are two different types of font mixins.
- Heading and Copy styles which are the font with added paddings to ensure a consistent baseline vertical grid.
- Core styles which are base font styles with no extra padding.
The following heading and copy styles exist:
heading-80heading-48heading-36heading-27heading-24copy-19copy-16copy-14
h2 {
@include heading-27;
}
The following core styles exist:
core-80core-48core-36core-27core-24core-19core-16core-14
@include core-[size]($line-height, $line-height-640)
$line-height and $line-height-640 are both optional. When used it is
recomended to pass a fraction in for readability.
h1 {
@include core-48;
}
h2 {
@include core-24($line-height: (50/24), $line-height-640: (18/16));
}
Tabular numbers have numerals of a standard fixed width. As all numbers have the same width, sets of numbers may be more easily compared. We recommend using them where different numbers are likely to be compared, or where different numbers should line up with each other, eg in tables.
$tabular-numbers is an optional variable that may be passed to the heading, copy and core styles to use (or explicitly not use) tabular numbers. When no variable is passed, the default is non-tabular.
h1 {
@include core-48;
}
h2 {
@include core-24($tabular-numbers: true);
}
See an example of tabular numbers in a table
external-link-default sets up the background image for all external links.
This should be included on the default link style for a project.
After setting the default, apply includes from the following for different font sizes:
external-link-12external-link-12-no-hoverexternal-link-13external-link-13-no-hoverexternal-link-14external-link-14-bold-no-hoverexternal-link-16external-link-16-bold-no-hoverexternal-link-19external-link-19-no-hover
external-link-heading is a unique style a background image for headings to groups of external links.
This uses the file-url helper which will by default output an image-url to
be used with Compass or Rails Asset Pipeline, if you want to use a static path
then set the $path variable to point to the public location of the toolkit
image assets.
For a set style:
@include external-link-[style]
For a specific font size:
@include external-link-[size]-[weight]-[no-hover]
/* Default link style */
a[rel="external"] {
@include external-link-default;
@include external-link-19;
}
th.external-link {
@include external-link-heading;
}
.inner a[rel="external"] {
@include external-link-16;
}
.departments a[rel="external"] {
@include external-link-16-bold-no-hover;
}

A mixin for creating buttons in the GOV.UK style.
@mixin button($colour)
$colour the background colour of the button (default is $green).
.button{
@include button;

.button-secondary{

}
.button-warning{
@include button($red);

The button text colour is set by the mixin to either light or dark, depending on the button background colour.
If you're applying these styles to non form elements, adding a class of 'disabled' to the element will emulate the disabled button style.
