Badges

.dcf-badge

This includes styles common to all badges and requires the addition of one of the following modifier classes to fully style a badge.

Roundrect Badges

.dcf-badge-roundrect

Use this modifier for a badge with roundrect shape.

Pill Badges

.dcf-badge-pill

Use this modifier for a badge with pill shape.

Blockquotes

.dcf-blockquote

Like inline quotes (<q>), the blockquote component automatically adds quotation marks—no need to add your own.

.dcf-attribution

To attribute the source of a quote, put the attribution in a <footer> element with the dcf-attribution class. It will automatically prepend an em dash (—) followed by a thin space ( ). If the attribution source comes from a creative work, it should be cited using the <cite> element and italicized with the <i> element to visually offset the title of the work from the rest of the attribution.

Cards

.dcf-card

A card is a commonly-used design pattern that groups related content in a container that resembles a physical playing card.

.dcf-card-block

The card block provides padding for text inside the card. Card contents that need to span the full width (like an image) should be placed outside of the card block.

Optionally, a card can be turned into a link. However, there are usability and accessibility issues with simply wrapping a card with an <a>. Instead, use the following classes and JavaScript to enable this functionality.

.dcf-card-as-link

Add to a card to turn the whole card into a link.

.dcf-card-link

The card needs a link defined to be used for the whole card. Apply this class to your source link.

Example Card

Integer posuere erat a ante venenatis dapibus posuere velit aliquet. Integer posuere erat a ante venenatis dapibus posuere velit aliquet. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed posuere consectetur est at lobortis. Aenean lacinia bibendum nulla sed consectetur.

Code

.dcf-pre

Retain code styling for multiple lines of code wrapped with <pre> element.

<p>Morbi leo risus, porta ac consectetur ac, vestibulum at eros.</p>
<p>Nulla vitae elit libero, a pharetra augue.</p>

Related: Code (Elements)

Datepickers

.dcf-datepicker

This class is applied to the wrapper <div> and is what the JavaScript targets to add functionality.

<form class="dcf-form" action="#" method="get">
  <div class="dcf-datepicker">
    <label for="sample-date">Date 2</label>
    <input id="sample-date" type="text" name="sample-date">
  </div>
</form>
<script>
  window.addEventListener('inlineJSReady', function() {
    WDN.initializePlugin('datepickers');
  }, false);
</script>

Note: Be sure to replace sample-date with an id and name of your own.

Related: Buttons (Components), Forms (Elements), Forms (Components), Input Groups (Components)

Figures

.dcf-figcaption

Figures do not require any additional classes, but .dcf-figcaption provides consistent styles for the <figcaption>. It reduces the font-size and lightens the text to help distinguish it from body copy. Use utility classes to add margins or padding as needed by the content in your <figure>.

Related: Figures (Elements), Images (Elements), Display (Utilities), Margins (Utilities), Padding (Utilities), Font Size (Utilities)

Forms

.dcf-form

Style a form and its children.

.dcf-form-group

Wrap groups of form elements (such as a label and input pair) to visually offset them from other form elements.

.dcf-form-controls-inline

At the small breakpoint, display labels and form controls inline (as space allows) instead of stacked.

.dcf-form-help

Formats help/description text that displays adjacent to a form element.

.dcf-required

Indicate that an adjacent form input is required to submit the form.

.dcf-input-checkbox

.dcf-input-radio

Wrap a checkbox or radio input and label pair for consistent cross-browser styling.

Unless you are using an input group with a button, labels should be placed above the corresponding text fields. Form fields and buttons should be presented in a left-aligned, single column layout so users aren't required to visually reorient themselves when scanning the form.

Use of Reset and Cancel buttons is discouraged.

Headings

Subheads

.dcf-subhead

A subhead is smaller and slightly lighter in appearance than a heading. Change the order of headings and subheads by wrapping them in a <div class="dcf-d-flex dcf-flex-col"></div> and adding order classes (.dcf-1st, .dcf-2nd, et al.) to the headings and subheads.

Related: Headings (Elements), Display (Utilities), Flexbox (Utilities), Order (Utilities)

Input Groups

.dcf-input-group

An input group prepends or appends text or a button to a text input. The form label must be placed outside of the input group. It can be vertically aligned with the input group by adding .dcf-flex and .dcf-ai-center to the input group's parent element.

Input Groups With Add-ons

.dcf-input-group-addon

An add-on provides additional context for a text input in a form. It can be placed before and/or after the text input.

Input Groups With A Button

If a form consists of a single field and button, consider using an input group for a more compact layout.

<label for="dcf-input-group-button-input">Label</label>
<div class="dcf-input-group">
  <input id="dcf-input-group-button-input">
  <button class="dcf-btn dcf-btn-primary" type="submit">Submit</button>
</div>

Lists

Bare Lists

.dcf-list-bare

This removes the left padding from a list and removes numbers from ordered lists or bullets from unordered lists.

Inline Lists

.dcf-list-bare

Remove left padding and list styles for the inline list.

.dcf-list-inline

Change the display of list items to inline-block and add right margin to all but the last list item.

Inline lists are also used to create pagination:

Related: Lists (Elements)

Modals

.dcf-modal

Each modal requires a unique id which must also match the value of the data-opens-modal attribute of any button(s) that will open the modal. This also functions as the overlay background of the open modal.

.dcf-modal-wrapper

This wrapper includes the modal header and modal content and excludes the modal overlay background.

.dcf-modal-header

The header contains the modal’s heading and the button to close the modal.

.dcf-modal-content

Modal content should be placed inside this <div>.

.dcf-btn-toggle-modal

This button toggles a modal. Its data-toggles-modal attribute value should match the id of the target modal to toggle. The disabled attribute must be included. If the JavaScript fails to load, modals are inoperable and the disabled attribute conveys to users the button’s disabled state. If/when the JavaScript loads, it will remove the disabled attribute.

.dcf-btn-close-modal

This button is located in the modal content and closes the currently open modal.

While developers can – and should – add classes to style modals as needed, at a minimum, a modal requires the following markup for functionality:

<button class="dcf-btn-toggle-modal" data-toggles-modal="my-unique-modal-id" type="button" disabled>Toggle Modal</button>
<div class="dcf-modal" id="my-unique-modal-id" hidden>
  <div class="dcf-modal-wrapper">
    <div class="dcf-modal-header">
      <h2>Your modal heading</h2>
      <button class="dcf-btn-close-modal">Close</button>
    </div>
    <div class="dcf-modal-content">
      <!-- Modal content goes here -->
    </div>
  </div>
</div>

If a modal contains a video, the video will automatically pause playback when the modal is closed.

Notices

.dcf-notice

This includes styles common to all notices and requires one of the following modifier classes to fully style a notice.

.dcf-notice-info

This notice is for general informational content.

.dcf-notice-success

This notice signals completion of a successful action to a user.

.dcf-notice-warning

This notice should be used to warn users to proceed with caution.

.dcf-notice-danger

This notice indicates an error or dangerous content.

By default dcf-header and dcf-main don't have position: relative set so the overlay notices just appear at the top of the page. To reproduce: add the code to a notice

data-overlay="dcf-header"

This notice overlays the header.

data-overlay="dcf-main"

This notice overlays the maincontent.

<div class="dcf-notice dcf-notice-info" hidden>
  <h2>Info</h2>
  <div>This is additional information for this notice.</div>
</div>
<div class="dcf-notice dcf-notice-success" hidden>
  <h2>Success!</h2>
  <div>You've successfully completed an action.</div>
</div>
<div class="dcf-notice dcf-notice-warning" hidden>
  <h2>Warning!</h2>
  <div>Proceed with caution.</div>
</div>
<div class="dcf-notice dcf-notice-danger" hidden>
  <h2>Danger!</h2>
  <div>Uh-oh. Something wrong happened.</div>
</div>
<div class="dcf-notice dcf-notice-info" hidden data-overlay="dcf-header">
  <h2>I'm Floating!</h2>
  <div>This notice overlays the header.</div>

  window.addEventListener('inlineJSReady', function() {
    WDN.initializePlugin('notice');
  }, false);
</script>

Pagination

Pagination requires a minimal amount of code from the developer. JavaScript handles the output of all the necessary attributes for state management and accessibility. Because pagination is, by its nature, an ordered collection of links, be sure to use an ordered list instead of an unordered list.

.dcf-pagination

This class is applied to the <nav> element and is what the JavaScript targets to add functionality.

.dcf-pagination-first

Adds a leftwards arrow to bar Unicode glyph before the button text.

.dcf-pagination-prev

Adds a leftwards arrow Unicode glyph before the button text.

.dcf-pagination-selected

.dcf-pagination-ellipsis

These two classes add padding around the text to match adjacent button padding.

.dcf-pagination-next

Adds a rightwards arrow Unicode glyph after the button text.

.dcf-pagination-last

Adds a rightwards arrow to bar Unicode glyph after the button text.

<nav class="dcf-pagination">
  <ol class="dcf-list-bare dcf-list-inline">
    <li><a class="dcf-pagination-first" href="#">First</a></li>
    <li><a class="dcf-pagination-prev" href="#">Prev</a></li>
    <li><a href="#">1</a></li>
    <li><a href="#">2</a></li>
    <li><span class="dcf-pagination-selected">3</span></li>
    <li><span class="dcf-pagination-ellipsis">…</span></li>
    <li><a class="dcf-pagination-next" href="#">Next</a></li>
    <li><a class="dcf-pagination-last" href="#">Last</a></li>
  </ol>
</nav>
<script>
  window.addEventListener('inlineJSReady', function() {
    WDN.initializePlugin('pagination');
  }, false);
</script>

Popups

Popups can be configured to open content when the user clicks on – or, optionally, hovers over – a button. Popup content is displayed below the toggle button by default, but can be positioned on any side of the toggle button. Triangle-shaped points can optionally be added to popup content, and those points can be aligned to the start, center or end of the popup. No additional JavaScript is required to initialize popups. Because they are used in the Visit / Apply / Give links in the header, they are included by default in the framework.

.dcf-popup

This class is applied to the wrapper <div> and is what the JavaScript targets to add functionality.

.dcf-btn-toggle-popup

This button toggles the display of a popup.

.dcf-popup-content

Popup content should be placed inside this <div>.

.dcf-btn-close-popup

Placed inside the popup content, this optional button provides an additional method for closing the popup.

data-hover="true"

This optional data-* attribute is placed on the <div class="dcf-popup"> and toggles a popup on hover in addition to button click.

data-point="true"

This optional data-* attribute is placed on the <div class="dcf-popup"> and adds a (triangle) point to the popup content.

data-position="*"

This optional data-* attribute is placed on the <div class="dcf-popup"> and positions the popup content on any side of the toggle button. Valid values are top, right, bottom and left. By default the popup is positioned to the bottom of the button.

data-alignment="*"

This optional data-* attribute is placed on the <div class="dcf-popup"> and controls the position of the (triangle) point on the popup content. Valid values are start, center and end.

<div class="dcf-popup" data-point="true">
  <button class="dcf-btn dcf-btn-primary dcf-btn-toggle-popup">Toggle Popup</button>
  <div class="dcf-popup-content dcf-w-12 dcf-pt-4 dcf-pr-5 dcf-pb-4 dcf-pl-5 dcf-rounded dcf-bg-overlay-dark unl-cream">
    <p class="dcf-txt-xs">Maecenas sed diam eget risus varius blandit sit amet non magna. Nulla vitae elit libero, a pharetra augue.</p>
    <button class="dcf-btn dcf-btn-secondary dcf-btn-close-popup">Close Popup</button>
  </div>
</div>

Slideshows

Slideshows require a minimal amount of code from the developer. JavaScript handles the output of all the necessary attributes for state management and accessibility. Each slideshow requires a list of slides to be placed inside a wrapper <div>. The list of slides may be either an ordered or unordered list, depending on your content. If your image requires a caption, use a <figcaption> inside of a <figure> (as shown in the sample code below). If your image doesn’t require a caption, do not use a <figure>.

.dcf-slideshow

This class is applied to the wrapper <div> and is what the JavaScript targets to add functionality.

<div class="dcf-slideshow">
  <ul>
    <li>
      <figure>
        <div class="dcf-ratio dcf-ratio-16x9 dcf-ratio-1x1@sm dcf-ratio-16x9@lg">

Tables

Tables in the framework are optimized for readability by reducing unnecessary ornamentation and placing an emphasis on the content itself. Richard Rutter's article "Web Typography: Designing Tables to be Read, Not Looked At" (excerpted from his book, Web Typography) is an excellent resource on the subject.

.dcf-table

The table font-size is slightly smaller than the body copy. Padding and borders are also added.

Note: A table must have a defined width for the .dcf-table-fixed utility to work. Use a width utility class (e.g., .dcf-w-100%) with .dcf-table-fixed on your desired <table>.

Bordered Tables

.dcf-table-bordered

The bordered table adds borders to all cells in the table.

Striped Tables

.dcf-table-striped

The striped table adds a subtle background color to alternating rows in the table.

Responsive Tables

.dcf-table-responsive

Responsive table contents display “stacked” at narrow screen widths.

This is a responsive striped table.

Image	Amount	Year	Description
	$2.00	1984	Nullam id dolor id nibh ultricies vehicula ut id elit
	$999.99	1999	Integer posuere erat a ante venenatis dapibus posuere velit aliquet. Etiam porta sem malesuada magna mollis euismod. Nullam quis risus eget urna mollis ornare vel eu leo. Etiam porta sem malesuada magna mollis euismod.
	$1,000,000.01	2001	Donec ullamcorper nulla non metus auctor fringilla
	$.01	2020	Nulla vitae elit libero, a pharetra augue

Scrollable Tables

Wrap your table in a <div class="dcf-overflow-x-auto" tabindex="0">.

Tabs

Tabs require a minimal amount of code from the developer. JavaScript handles the output of all the necessary attributes for state management and accessibility. Each tab group requires a wrapper <div> and a heading, which may be visually hidden if necessary. The list of tabs may be either an ordered or unordered list, depending on your content. The tab panels may be either <div>s or <sections>s, however <div>s will suffice most of the time.

.dcf-tabs

This class is applied to the wrapper <div> and is what the JavaScript targets to add functionality.

.dcf-tabs-responsive

This optional class can be added to stack tabs vertically at narrower viewport widths.

Be sure to give each tab panel a unique id and enter that same value in the corresponding tab’s href.

The <script> to initialize the tabs component is required only once per page, even if more than one tab group is included on the page.

<div class="dcf-tabs dcf-tabs-responsive">
