Box
A .Box
is a container with a a white background ,a light gray border, and rounded corners. By default there are no additional styles such as padding, these can be added as needed with utility classes. Other styles and layouts can be achieved with box elements and modifiers shown in the documentation below.
<div class="Box">
This is a box.
</div>
Box elements
Box elements include Box-header
, Box-body
, and Box-footer
. These elements include borders and consistent padding. Optionally, you can include use Box-title
which applies a bold font-weight the heading.
<div class="Box">
<div class="Box-header">
<h3 class="Box-title">
Box title
</h3>
</div>
<div class="Box-body">
Box body
</div>
<div class="Box-footer">
Box footer
</div>
</div>
Box row
Use Box-row
to add rows with borders and maintain the same padding. Box rows have a lighter border to give contrast between the header and footer.
Note: Box rows have some reliance on markup structure in order to target the first and last rows, therefore using an unordered list is recommended. See box row markup structure for more information.
<div class="Box">
<ul>
<li class="Box-row">
Box row one
</li>
<li class="Box-row">
Box row two
</li>
<li class="Box-row">
Box row three
</li>
<li class="Box-row">
Box row four
</li>
</ul>
</div>
Rows can be used with or without Box-header
, Box-footer
, or Box-body
.
<div class="Box">
<div class="Box-header">
Box header
</div>
<div class="Box-body">
<strong>Box body</strong>
</div>
<ul>
<li class="Box-row">
Box row one
</li>
<li class="Box-row">
Box row two
</li>
<li class="Box-row">
Box row three
</li>
<li class="Box-row">
Box row four
</li>
</ul>
<div class="Box-footer">
Box footer
</div>
</div>
Box row markup structure
Box rows have some reliance on markup structure in order to target the first and last rows. Box rows are given a top border that is lighter in color than other box elements so the first row is targeted to apply a darker border color. An inner border-radius is applied to the first and last rows that that row corners don't poke outside the Box
, this can be particularly noticeable when using a highlight on box rows.
Using an unordered list is recommended in order to target the first and last rows, however, if you need to use a <div>
for your rows, you may want to place your rows inside a parent <div>
so that the first and last rows are styled appropriately.
<div class="Box">
<div class="Box-header">
Box header
</div>
<!-- This wrapping div ensures the first and last rows can be targeted for styling. -->
<div>
<div class="Box-row">Box row using a div</div>
<div class="Box-row">Box row using a div</div>
</div>
</div>
Box padding density
You can changed the padding density of the box component.
Use Box--condensed
to apply a more condensed line-height and reduce the padding on the Y axis.
<div class="Box Box--condensed">
<div class="Box-header">
<h3 class="Box-title">
Box title
</h3>
</div>
<div class="Box-body">
Box body
</div>
<ul>
<li class="Box-row">
Box row one
</li>
<li class="Box-row">
Box row two
</li>
</ul>
<div class="Box-footer">
Box footer
</div>
</div>
Use Box--spacious
to increase padding and increase the title font size.
You may want to increase the overall font size to work with the larger padding, in this example the default body font size is increased to 16px using the f4
typography utility.
<div class="Box Box--spacious f4">
<div class="Box-header">
<h3 class="Box-title">
Box title
</h3>
</div>
<div class="Box-body">
Box body
</div>
<ul>
<li class="Box-row">
Box row one
</li>
<li class="Box-row">
Box row two
</li>
</ul>
<div class="Box-footer">
Box footer
</div>
</div>
Blue box theme
Use Box--blue
to style the box borders and box header in blue.
<div class="Box Box--blue">
<div class="Box-header">
Box header
</div>
<ul>
<li class="Box-row">
Box row one
</li>
<li class="Box-row">
Box row two
</li>
</ul>
<div class="Box-footer">
Box footer
</div>
</div>
Blue box header theme
Use Box-header--blue
to add to change the header border and background to blue.
<div class="Box">
<div class="Box-header Box-header--blue">
<h3 class="Box-title">Box with blue header</h3>
</div>
<div class="Box-body">
Box body
</div>
</div>
Box danger theme
Use Box--danger
to apply a red border to the outside of the box. This theme is helpful for communicating destructive actions.
Note: Box-danger
only works with either Box-row
's or Box-body
.
<div class="Box Box--danger">
<div class="Box-row">
Row one
</div>
<div class="Box-row">
Row two
</div>
</div>
Box-danger
is often paired with a red heading. See the subhead docs for more information.
<div class="Subhead border-bottom-0">
<h2 class="Subhead-heading Subhead-heading--danger">Danger zone</h2>
</div>
<div class="Box Box--danger">
<div class="Box-body">
Box body
</div>
</div>
Row themes
You can change the background color for individual rows, or change the color on hover or navigation focus.
<div class="Box">
<div class="Box-row Box-row--gray">
.Box-row--gray
</div>
<div class="Box-row Box-row--hover-gray">
.Box-row--hover-gray
</div>
<div class="Box-row Box-row--yellow">
.Box-row--yellow
</div>
<div class="Box-row Box-row--hover-blue">
.Box-row--hover-blue
</div>
<div class="Box-row Box-row--blue">
.Box-row--blue
</div>
</div>
Use Box-row--focus-gray
or Box-row--focus-blue
when using along-side navigation-focus
if you want to highlight rows when using keyboard commands.
<div class="Box">
<div class="Box-row Box-row--focus-gray navigation-focus">
.Box-row--focus-gray and .navigation-focus
</div>
<div class="Box-row Box-row--focus-gray">
.Box-row--focus-gray
</div>
<div class="Box-row Box-row--focus-blue navigation-focus">
.Box-row--focus-blue and .navigation-focus
</div>
<div class="Box-row Box-row--focus-blue">
.Box-row--focus-blue
</div>
</div>
Box row unread
Use .Box-row-unread
to apply a blue vertical line highlight for indicating a row contains unread items.
<div class="Box">
<div class="Box-row">
Box row
</div>
<div class="Box-row Box-row--unread">
Box row unread
</div>
<div class="Box-row">
Box row
</div>
</div>
Box row link
Use .Box-row-link
when you want a link to appear dark gray and blue on hover on desktop, and remain a blue link on mobile. This is useful to indicate links on mobile without having hover styles.
<div class="Box">
<div class="Box-row">
<a class="Box-row-link" href="#box-row-link">Box row link</a>
</div>
</div>
Dashed border
Use the border-dashed
utility to apply a dashed border to a box.
<div class="Box border-dashed p-2">
A box with a dashed border
</div>
Boxes with flash alerts
Use flash-full
for flash alert inside a box to remove the rounded corners. Place the flash alert above the Box-body
and underneath the Box-header
.
Flash alerts come in three different colors and can be used with icons and buttons, see the alert documentation for more information.
<div class="Box">
<div class="Box-header">
Box header
</div>
<div class="flash flash-full">
<button class="flash-close js-flash-close"><%= octicon "x" %></button>
Flash message with close button.
</div>
<div class="flash flash-full flash-success">
<%= octicon("check") %> Flash success with an icon.
</div>
<div class="flash flash-full flash-warn">
<%= octicon("alert") %> Flash warning with an icon.
</div>
<div class="flash flash-full flash-error">
Flash error inside a Box.
</div>
<div class="Box-body">
Box body
</div>
</div>
Boxes with icons
Use Box-btn-octicon
with btn-octicon
when you want the icon to maintain the same padding as other box elements. This selector offsets margin to ensure it lines up on the left and right sides of the box so you may need to add padding neighboring elements.
<div class="Box">
<div class="Box-body">
<span class="pr-2">Box body</span>
<button href="#" class="Box-btn-octicon btn-octicon"><%= octicon("pencil") %></button>
</div>
</div>
It's common to want to float icons to the far left or right and stop the Box-title
from wrapping underneath. To do this you'll need to create a media object with utilities. Add clearfix
to the surrounding div (this could be the header, body, or rows), add overflow-hidden
to the title (or other text element), and float the icons as desired.
<div class="Box">
<div class="Box-header clearfix">
<button href="#" class="Box-btn-octicon btn-octicon float-right"><%= octicon("x") %></button>
<h3 class="Box-title overflow-hidden pr-3">A very long title that wraps onto multiple lines without overlapping or wrapping underneath the icon to it's right</h3>
</div>
<div class="Box-body">
Box body
</div>
</div>
<div class="Box">
<div class="Box-row clearfix">
<button href="#" class="Box-btn-octicon btn-octicon float-left"><%= octicon "check" %></button>
<p class="overflow-hidden pl-3">A very long paragraph that wraps onto multiple lines without overlapping or wrapping underneath the icon to it's left</p>
</div>
</div>
Box headers with counters
Use a counter with a background that works against the contrast of the box header. The default counter colors do not stand out well against the header background so we suggest using one of the following styles:
Use Counter--gray
for a counter with a gray background and dark gray text.
<div class="Box">
<div class="Box-header">
<h3 class="Box-title">
Box title
<span class="Counter Counter--gray">12</span>
</h3>
</div>
<div class="Box-body">
Box body
</div>
</div>
Use Counter--gray-dark
for a counter with a dark gray background and white text.
<div class="Box">
<div class="Box-header">
<h3 class="Box-title">
Box title
<span class="Counter Counter--gray-dark">12</span>
</h3>
</div>
<div class="Box-body">
Box body
</div>
</div>
Form elements and buttons in boxes
To achieve different layouts when adding buttons or form elements to boxes we suggest you use utilities to achieve the layout you want. Here's some common examples:
Use flexbox utilities to center align items, and avoid using floats by using flex-auto
to have the text fill the remaining space so that the button rests on the far right.
<div class="Box Box--condensed">
<div class="Box-header d-flex flex-items-center">
<h3 class="Box-title overflow-hidden flex-auto">
Box title
</h3>
<button class="btn btn-primary btn-sm">
Button
</button>
</div>
<div class="Box-body">
Box body
</div>
</div>
A similar approach can be used for buttons with multiple lines of text within a row.
<div class="Box">
<div class="Box-row d-flex flex-items-center">
<div class="flex-auto">
<strong>Row title</strong>
<div class="text-small text-gray-light">
Description
</div>
</div>
<button type="button" class="btn btn-primary" name="button">View</button>
</div>
<div class="Box-row d-flex flex-items-center">
<div class="flex-auto">
<strong>Row title</strong>
<div class="text-small text-gray-light">
Description
</div>
</div>
<button type="button" class="btn btn-primary" name="button">View</button>
</div>
<div class="Box-row d-flex flex-items-center">
<div class="flex-auto">
<strong>Row title</strong>
<div class="text-small text-gray-light">
Description
</div>
</div>
<button type="button" class="btn btn-primary" name="button">View</button>
</div>
</div>
Using flexbox along with form, button, and link styles, you can create more complex box headers for things like bulk actions and sorting.
<div class="Box">
<div class="Box-header d-flex flex-items-center">
<form class="flex-auto">
<label>
<input class="mr-1" type="checkbox">
Check it
</label>
</form>
<button class="btn-link select-menu-button muted-link">
Select menu
</button>
</div>
<div class="Box-body">
Box body
</div>
</div>
You can put forms in boxes. Often form submission buttons are aligned to the bottom right of the form which you can do with text-right
instead of using floats.
<div class="Box">
<div class="Box-header">
<h3 class="Box-title">
Example form title
</h3>
</div>
<form>
<div class="Box-body">
<dl class="form-group">
<dt><label>Example label</label></dt>
<dd><input class="form-control" type="text"></dd>
</dl>
<div class="form-checkbox">
<label>
<input type="checkbox" checked="checked">
Yes please
</label>
</div>
</div>
<div class="Box-footer text-right">
<button class="btn btn-secondary mr-1">
Cancel
</button>
<button class="btn btn-primary">
Submit
</button>
</div>
</form>
</div>
When a box is all by itself centered on a page you can use column widths to control the width of the box. If needed, break the mold a little and use typography utilities instead of the built in box title styles.
<div class="Box Box--spacious col-6 mx-auto text-center">
<form>
<div class="Box-body">
<h3 class="f1-light">
Example form
</h3>
<dl class="form-group mb-4">
<dt><label>Example label</label></dt>
<dd><input class="form-control" type="text"></dd>
</dl>
<button class="btn btn-primary btn-block">
Submit
</button>
</div>
</form>
</div>
Box patterns can also be made with, and modified with border utilities.
