Built upon Bootstrap's Reboot, a collection of element-specific CSS to provide a consistent visual baseline across browsers.


Part of Figuration's job is to provide an elegant, consistent, and simple baseline to build upon. We use Reboot, a collection of element-specific CSS changes in a single file, to kickstart that.

Borrowed from Bootstrap, Reboot heavily builds upon Normalize.css, providing many HTML elements with somewhat opinionated styles using only element selectors. Additional styling is done only with classes. For example, we reboot some <table> styles for a simpler baseline and later provide .table, .table-bordered, and more.

Here are our guidelines and reasons for choosing what to override in Reboot:

  • Update some browser default values to use rems instead of ems for scalable component spacing.
  • Avoid margin-top. Vertical margins can collapse, yielding unexpected results. More importantly though, a single direction of margin is a simpler mental model.
  • For easier scaling across device sizes, block elements should use rems for margins.
  • Keep declarations of font-related properties to a minimum, using inherit whenever possible.

Page Defaults

The <html> and <body> elements are updated to provide better page-wide defaults. More specifically:

  • The box-sizing is globally set on every element—including *::before and *::after, to border-box. This ensures that the declared width of element is never exceeded due to padding or border.
  • No base font-size is declared on the <html>, but a 16px browser default is assumed. font-size: 1rem on the <body> for easy responsive type-scaling via media queries while respecting user preferences allowing for a more accessible approach. This browser default can be overridden by modifying the $font-size-root variable.
  • The <body> also sets a global font-family, line-height, and text-align. This is inherited later by some form elements to prevent font inconsistencies.
  • For safety, the <body> has a declared background-color, defaulting to #fff.

Native Font Stack

Figuration uses a "native font stack", sometimes called a "system font stack", for optimum text rendering on every device and OS. These system fonts have been designed specifically with today's devices in mind, with improved rendering on screens, variable font support, and more. Read more about native font stacks in this Smashing Magazine article.

// macOS and iOS
// Windows
"Segoe UI",
// Android
// older macOS and iOS
"Helvetica Neue",
// Linux
"Noto Sans",
"Liberation Sans",
// Basic web fallback
// Sans serif fallback
// Emoji fonts
"Apple Color Emoji",
"Segoe UI Emoji",
"Segoe UI Symbol",
"Noto Color Emoji"

Note that because the font stack includes emoji fonts, many common symbol/dingbat unicode characters will be rendered as multi-colored pictographs. Their appearance will vary, depending on the style used in the browser/platform's native emoji font, and they won't be affected by any CSS color styles.

This font-family is applied to the <body> and automatically inherited globally throughout Figuration. To switch the global font-family, update $font-family-base and recompile Figuration.

Headings and Paragraphs

All heading elements—e.g., <h1>—and <p> are reset to have their margin-top removed. Headings have margin-bottom: .5rem added and paragraphs margin-bottom: 1rem for easy spacing.

h1 heading

Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

h2 heading

Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

h3 heading

Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

h4 heading

Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

h5 heading

Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

h6 heading

Curabitur blandit tempus porttitor. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.


All lists—<ul>, <ol>, and <dl>—have their margin-top removed and a margin-bottom: 1rem. Nested lists have no margin-bottom.

For simpler styling, clear hierarchy, and better spacing, description lists have updated margins. <dd>s reset margin-left to 0 and add margin-bottom: .5rem. <dt>s are bolded.

Description lists
A description list is perfect for defining terms.
Vestibulum id ligula porta felis euismod semper eget lacinia odio sem.
Donec id elit non mi porta gravida at eget metus.
Malesuada porta
Etiam porta sem malesuada magna mollis euismod.

Preformatted Text

The <pre> element is reset to remove its margin-top and use rem units for its margin-bottom.

.example-element {
  margin-bottom: 1rem;


Tables are slightly adjusted to style <caption>s, collapse borders, and ensure consistent text-align throughout. Additional changes for borders, padding, and more come with the .table class.

This is an example table, and this is its caption to describe the contents.

Various form elements have been rebooted for simpler base styles. Here are some of the most notable changes:

  • <fieldset>s have no borders, padding, or margin so they can be easily used as wrappers for individual inputs or groups of inputs.
  • <legend>s, like fieldsets, have also been restyled to be displayed as a heading of sorts.
  • <label>s are set to display: inline-block to allow margin to be applied.
  • <input>s, <select>s, <textarea>s, and <button>s are mostly addressed by Normalize, but Reboot removes their margin and sets line-height: inherit, too.
  • <textarea>s are modified to only be resizable vertically as horizontal resizing often "breaks" page layout.

These changes, and more, are demonstrated below.

Example legend


Date, Time, and Color Input Support

Be aware that not all browsers support the date and time or color input types.

Pointers On Buttons

Reboot includes an enhancement for role="button" to change the default cursor to pointer. Add this attribute to elements to help indicate elements are interactive. This role isn't necessary for <button> elements, which get their own cursor change.

Non-button element button
<span role="button" tabindex="0">Non-button element button</span>

Misc Elements


The <address> element is updated to reset the browser default font-style from italic to normal. line-height is also now inherited, and margin-bottom: 1rem has been added. <address>s are for presenting contact information for the nearest ancestor (or an entire body of work). Preserve formatting by ending lines with <br>.

Full Name


The default margin on blockquotes is 1em 40px, so we reset that to 0 0 1rem for something more consistent with other elements.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title

Inline Elements

The <abbr> element receives basic styling to make it stand out amongst paragraph text.

Nulla attr vitae elit libero, a pharetra augue.

Inline Frame

<iframe>s have are set to border: 0; so there is no need for a frameborder="0" attribute.


The default cursor on summary is text, so we reset that to pointer to convey that the element can be interacted with by clicking on it.

Even more details

Here are even more details about the details.

HTML5 [hidden] Attribute

HTML5 adds a new global attribute named [hidden], which is styled as display: none by default. Borrowing an idea from PureCSS, we improve upon this default by making [hidden] { display: none !important; } to help prevent its display from getting accidentally overridden. While [hidden] isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem.

<input type="text" hidden>

jQuery Incompatibility

[hidden] is not compatible with jQuery's $(...).hide() and $(...).show() methods. Therefore, we don't currently especially endorse [hidden] over other techniques for managing the display of elements.

To merely toggle the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document, use the .invisible class instead.
