Get started with OUDS Web

OUDS Web is based on Bootstrap: a powerful, feature-packed frontend toolkit. Build anything—from prototype to production—in minutes.

Quick start

Get started by including OUDS Web’s production-ready CSS and JavaScript via CDN without the need for any build steps. See it in practice with this OUDS Web 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>OUDS Web demo</title>
  </head>
  <body>
    <h1>Hello, world!</h1>
  </body>
</html>

  

            
          

Include OUDS Web’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, popovers, and tooltips) before the closing </body>. Learn more about our CDN links.

    <!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>OUDS Web demo</title>
    <link href="https://cdn.jsdelivr.net/npm/@ouds/web-orange@1.5.0/dist/css/ouds-web.min.css" rel="stylesheet" integrity="sha384-pASwsNEkGwpJibll6DpHIhi7kAiLDGTLmBJ5GVL1ZZe1iAGMLtrNQwksOznxX+gV" crossorigin="anonymous" />
  </head>
  <body>
    <h1>Hello, world!</h1>
    <script src="https://cdn.jsdelivr.net/npm/@ouds/web-common@1.5.0/dist/js/ouds-web.bundle.min.js" integrity="sha384-vxOsFAM8abhNsTIB3U20VNqClqsZLa00eytCnuiPOVWqEs580qc8lVd6wtst2DoS" crossorigin="anonymous"></script>
  </body>
</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.

    <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.11.8/dist/umd/popper.min.js" integrity="sha384-I7E8VVD/ismYTF4hNIPjVp/Zjvgyol6VFvRkX/vR+Vc4jQkC+hVqc2pM8ODewa9r" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/@ouds/web-common@1.5.0/dist/js/ouds-web.min.js" integrity="sha384-W7aPSNVvcO7DVt/YZ5SYrzkMiig2Mi0hQYrf2HSVwPffFA4jRDQVsf49fId3jXdl" crossorigin="anonymous"></script>

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

CDN links

As reference, here are our primary CDN links.

Description	URL
CSS	`https://cdn.jsdelivr.net/npm/@ouds/web-orange@1.5.0/dist/css/ouds-web.min.css`
JS	`https://cdn.jsdelivr.net/npm/@ouds/web-common@1.5.0/dist/js/ouds-web.bundle.min.js`

You can also use the CDN to fetch any of our additional builds listed in the Contents page.

When using CDN links, be sure to use the integrity attribute to verify the correct files and versions. These hashes are unique to each file and version of OUDS Web, so when you update to a new version, be sure the integrity attribute is also updated.

We also include a crossorigin="anonymous" attribute to prevent CORS errors.

Using OUDS Web with AI coding agents

OUDS Web ships Agent Skills in the skills/ directory of the repository. These give AI coding agents (Claude Code, Cursor, GitHub Copilot, and others) procedural knowledge of OUDS Web, such as correct component markup, layout and utility classes, design tokens, and migration steps from Boosted, OB1, or older OUDS Web versions.

Install them in your project with the skills CLI:

npx skills add Orange-OpenSource/Orange-Boosted-Bootstrap/skills

This downloads the skills and configures them for use with your AI agent.

JS components

Here is a list of components that explicitly require our JavaScript and Popper for interactivity.

Important globals

OUDS Web 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

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

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

Viewport meta

OUDS Web 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.

`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.
