About Orange Brand

As Boosted is based on Bootstrap, you’ll find in Boosted all the Bootstrap’s components and their variants, but with an Orange branded look.

Among those inherited components and variants, some exist in the Orange Design System and fully respect its design specifications and some don’t. Those ones should not be used in your projects to ensure a consistent user experience throughout our Orange web services.

As for maintainability reasons we have to keep them in this documentation, we tagged them with red informational design callouts. They inform you of what should not be used from an Orange design point of view. They suggest, when available, a replacement solution and/or a link to the Orange Design System website to see other possibilities. Thanks for taking this information into account.

Design callouts message example:

Incompatibility with Orange Design System. More information

This checkbox variant should not be used because it does not respect the Orange Design System specifications.

From the Orange Design System point of view, checkboxes should be represented like in our Boosted Checks component. You can also refer to the Checkbox guidelines on on the Orange Design System website.

Quick start

Get started by including Boosted’s production-ready CSS and JavaScript via CDN without the need for any build steps. See it in practice with this Boosted CodePen demo.

Create a new index.html file in your project root. Include the <meta name="viewport"> tag as well for proper responsive behavior in mobile devices.

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Boosted demo</title>
  </head>
  <body>
    <h1>Hello, world!</h1>
  </body>
</html>

Include Boosted’s CSS and JS. Place the <link> tag in the <head> for our CSS, and the <script> tag for our JavaScript bundle (including Popper for positioning dropdowns, poppers, and tooltips) before the closing </body>. Learn more about our CDN links.

Boosted also provides Helvetica Neue fonts, limited to Orange brand usage: see NOTICE.txt for more information about Helvetica Neue license.

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

</html>

You can also include Popper and our JS separately. If you don’t plan to use dropdowns, popovers, or tooltips, save some kilobytes by not including Popper.

Hello, world! Open the page in your browser of choice to see your Boosted page. Now you can start building with Boosted by creating your own layout, adding dozens of components, and utilizing our official examples.

JS components

Curious which components explicitly require our JavaScript and Popper? Click the show components link below. If you’re at all unsure about the general page structure, keep reading for an example page template.

Show components requiring JavaScript

Alerts for dismissing
Buttons for toggling states and checkbox/radio functionality
Carousel for all slide behaviors, controls, and indicators
Collapse for toggling visibility of content
Dropdowns for displaying and positioning (also requires Popper)
Footer for extending our Collapse plugin to implement responsive behavior
Modals for displaying, positioning, and scroll behavior
Navbar for extending our Collapse and Offcanvas plugins to implement responsive behaviors
Navs with the Tab plugin for toggling content panes
Offcanvases for displaying, positioning, and scroll behavior
Orange navbar for minimizing the header
Quantity selector for incrementing/decrementing number value
Scrollspy for scroll behavior and navigation updates
Toasts for displaying and dismissing
Tooltips and popovers for displaying and positioning (also requires Popper)

Required script

Boosted includes WICG’s :focus-visible polyfill to ensure an enhanced focus visibility for keyboard users while shutting down focus styles on active state. However, if you don’t need or want to use Boosted’s JavaScript files, you’ll still need to use the polyfill.

<script src="https://cdn.jsdelivr.net/npm/focus-visible@5.2.0/dist/focus-visible.min.js" integrity="sha384-xRa5B8rCDfdg0npZcxAh+RXswrbFk3g6dlHVeABeluN8EIwdyljz/LqJgc2R3KNA" crossorigin="anonymous"></script>

Important globals

Boosted employs a handful of important global styles and settings, all of which are almost exclusively geared towards the normalization of cross browser styles. Let’s dive in.

HTML5 doctype

Boosted requires the use of the HTML5 doctype. Without it, you’ll see some funky and incomplete styling.

<!doctype html>
<html lang="en">
  ...
</html>

Responsive meta tag

Boosted is developed mobile first, a strategy in which we optimize code for mobile devices first and then scale up components as necessary using CSS media queries. To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your <head>.

<meta name="viewport" content="width=device-width, initial-scale=1">

You can see an example of this in action in the quick start.

Box-sizing

For more straightforward sizing in CSS, we switch the global box-sizing value from content-box to border-box. This ensures padding does not affect the final computed width of an element, but it can cause problems with some third-party software like Google Maps and Google Custom Search Engine.

On the rare occasion you need to override it, use something like the following:

.selector-for-some-widget {
  box-sizing: content-box;
}

With the above snippet, nested elements—including generated content via ::before and ::after—will all inherit the specified box-sizing for that .selector-for-some-widget.

Learn more about box model and sizing at CSS Tricks.

Resource Hints

Resource hints are meant to optimize browser loading strategy, by either preloading assets, prefetching DNS or preconnecting to domains — but please use them carefully and only to hint resources you’ll really be using soon. It should be used for critical resources only.

`preload` fonts

<link rel="preload" href="dist/fonts/HelvNeue75_W1G.woff2" as="font" type="font/woff2" crossorigin="anonymous">
<link rel="preload" href="dist/fonts/HelvNeue55_W1G.woff2" as="font" type="font/woff2" crossorigin="anonymous">

`preconnect` to CDNs

<link rel="preconnect" href="https://cdn.jsdelivr.net" crossorigin="anonymous">

Reboot

For improved cross-browser rendering, we use Reboot to correct inconsistencies across browsers and devices while providing slightly more opinionated resets to common HTML elements.
