We use jQuery’s slim build, but the full version is also supported.
Curious which components explicitly require jQuery, our JS, and Popper.js? Click the show components link below. If you’re at all unsure about the general page structure, keep reading for an example page template.
boosted.bundle.min.js include Popper, and all of
boosted.bundle.min.js include focus-visible’s Polyfill — but not jQuery. For more information about what’s included in Boosted, please see our contents section.

- Dropdowns for displaying and positioning (also requires Popper.js)
- Modals for displaying, positioning, and scroll behavior
- Navbar for extending our Collapse plugin to implement responsive behavior

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

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.
Ressource 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.
