Get started with Boosted using the Boosted source and a template starter page.

About Orange Brand

All Boosted components are compliant with Orange Brand Guidelines. Some bootstrap features may not support the brand guidelines, partially or entirely. They are tagged in this documentation with the following warning, not brand compliant, use them at your own risks. Please note the entire bootstrap doc is preserved and enhancend when necessary with orange brand specifics, i.e. navbar page contains unsupported features, check out navbar orange page to find out what to use.

Quick start

Once you have downloaded boosted source files, copy-paste the stylesheet <link> into your <head> before all other stylesheets to load our CSS. You can also add orangeHelvetica and orangeIcons if needed, be careful both files are under copyright, see NOTICE.txt for more information.

Add our optional JavaScript plugins, jQuery, and Popper.js) near the end of your pages, right before the closing </body> tag. Be sure to place jQuery and Popper.js first, as our JavaScript plugins depend on them. While we use jQuery’s slim build in our docs, the full version is also supported.

And that’s it—you’re on your way to a fully Boosted by Orange site. If you’re at all unsure about the general page structure, keep reading for an example page template.

Starter template

Be sure to have your pages set up with the latest design and development standards. That means using an HTML5 doctype and including a viewport meta tag for proper responsive behaviors. Put it all together and your pages should look like this:

<!doctype html>
<html lang="en">
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta http-equiv="x-ua-compatible" content="ie=edge">

    <h1>Hello, world!</h1>

    <main id="content" role="main">
      My page content start here

    <!-- Optional JavaScript -->
    <!-- jQuery first, then Popper.js, then Boosted JS. -->
    <script src="" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

That’s all you need for overall page requirements. Visit the Layout docs or our official examples to start laying out your site’s content and components.

Important globals

Bootstrap employs a handful of important global styles and settings that you’ll need to be aware of when using it, all of which are almost exclusively geared towards the normalization of cross browser styles. Let’s dive in.

HTML5 doctype

Bootstrap requires the use of the HTML5 doctype. Without it, you’ll see some funky incomplete styling, but including it shouldn’t cause any considerable hiccups.

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

Responsive meta tag

Bootstrap 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, shrink-to-fit=no">

You can see an example of this in action in the starter template.


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.


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.
