Grid
The grid provides structure for website content. The flexible design adjusts for different devices.
Standard grid
Twelve-column grid with flexible column widths and fixed gutters. The width of the padding on the left and right edge of the grid depends on device size.
- 30px fixed gutter width
- Max width 1230px, background colors may bleed to edge
- Desktop: 30px padding on each side
- Tablet: 30px padding on each side
- Mobile: 15px padding on each side

</div>Breakpoints
Five major breakpoints standardize large-scale changes like navigation and sidebar behavior. Use other breakpoints as necessary.
-
xs: 0-600px -
sm: 601-900px -
med: 901-1020px -
lg: 1021-1230px -
xl: 1231px and up
Development
Warning: This document is written for people who might want to create a grid system using our SCSS mixins, and does not itself document how we have used our own mixins to create a grid system. Nor does it document how to use said grid system. This page probably needs a major re-write.
The grid component is a suite of variables and mixins that enables you to lay out a flexible 12-column grid with fixed-size gutters. (Column widths will expand and contract with the width of the page, but the gutter width remains constant.) The mixins are made to be used within your project’s SCSS code to give grid layout to your content without needing to use non-semantic grid classes.
For example, when creating a half-and-half layout, instead of applying classes to your column wrappers, like this:
<div class="col-half"> … </div>
<div class="col-half"> … </div>
You can give your wrappers semantic class names that describe their content, and apply the mixins to those semantic classes, like this:
<div class="description"> … </div>
<div class="illustration"> … </div>
.description,
.illustration {
.u-grid-column(1, 2);
}
Read on for more details on the variables and mixins this component provides.
Wrappers
Wrappers are centered containers with a max-width and outside left/right padding of ½ the gutter width on each side.
Sass mixin
@include u-grid-wrapper( @grid_wrapper-width: @grid_wrapper-width )
You can create a wrapper with max-width other than the default by passing a pixel value into the mixin.
Example
.main-wrapper {
@include u-grid-wrapper();
}
.wide-wrapper {
@include u-grid-wrapper( 1900px );
}
HTML code snippet
<div class="main-wrapper" style="background-color: #f9f9f9">This container now has left and right padding and a centered max width.</div>
<div class="wide-wrapper" style="background-color: #f9f9f9">This container is the same except it has a wider max-width.</div>Columns
Mixin
@include u-grid-column( $columns: 1, $total: $grid-total-columns )
Create a grid column that is $columns wide given $total total grid columns.
Grid columns use transparent borders to create the gutters of the grid,
so if you want a column to have a background or border, you’ll need to
add a wrapper just inside the column to be styled that way.
.main-wrapper {
@include u-grid-wrapper();
}
.half {
.u-grid-column(1, 2);
}
.styled {
border: 1px solid #999;
background: #EEE;
}
NOTE: cf-grid does not have a “row” concept. If you have a 12-column grid and place 24 columns inside a wrapper, cf-grid columns will automatically stack into two rows of 12.
HTML code snippet
<div class="main-wrapper">
<div class="half">I am half of my parent.</div>
<div class="half">
<div class="styled">I am half of my parent. I also have a border and background.</div>
</div>
</div>Nested columns
Since all grid columns have left and right gutters, you will notice undesirable offsetting when nesting columns. Normally this is removed with complex selectors or by adding classes to the first and last column per ‘row’.
In cf-grid, the way to get around this is by wrapping your columns
in a container that utilizes the .u-grid-nested-col-group() mixin.
This mixin uses negative left and right margins to
pull the columns back into alignment with parent columns.
Working this way allows you to easily create responsive grids. You are free to control the number of columns per “row” at different breakpoints without having to deal with the first and last columns of each row.
Mixin
.u-grid-nested-col-group()
Usage
.main-wrapper {
@include u-grid-wrapper();
}
.nested {
.u-grid-nested-col-group();
}
.half {
.u-grid-column(1, 2);
}

Turns an element into a cf-grid wrapper at 801px and above (e.g., <div class="wrapper">). Includes some explicit declarations for Internet Explorer 8 due to the fact that it doesn’t support media queries.
