Navbar

Documentation and examples for Boosted’s powerful, responsive navigation header, the navbar. Includes support for branding, navigation, and more, including support for our collapse plugin.

On this page

Incompatibility with Orange Design System. More information

This component explains the basic behavior, structure and concepts of navbars from a Bootstrap point of view. Some discrepancies exist with Boosted due to a different HTML structure. Moreover, Orange navbars have the same rendering in light and dark mode.

In order to build an Orange navbar please refer to Orange navbar.

How it works

Here’s what you need to know before getting started with the navbar:

Navbars require a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl|-xxl} for responsive collapsing and color scheme classes.
Navbars and their contents are fluid by default. Change the container to limit their horizontal width in different ways.
Use our spacing and flex utility classes for controlling spacing and alignment within navbars.
Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.
Ensure accessibility by using a <nav> element or, if using a more generic element such as a <div>, add a role="navigation" to every navbar to explicitly identify it as a landmark region for users of assistive technologies.
Indicate the current item by using aria-current="page" for the current page or aria-current="true" for the current item in a set.
New in v5.2.0: Navbars can be themed with CSS variables that are scoped to the .navbar base class. .navbar-light has been deprecated and .navbar-dark has been rewritten to override CSS variables instead of adding additional styles.

The animation effect of this component is dependent on the prefers-reduced-motion media query. See the reduced motion section of our accessibility documentation.

Supported content

Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:

.navbar-brand for Orange logo, and your product or project name.
.navbar-nav for a full-height and lightweight navigation (including support for dropdowns).
.navbar-toggler for use with our collapse plugin and other navigation toggling behaviors.
Flex and spacing utilities for any form controls and actions.
.navbar-text for adding vertically centered strings of text.
.collapse.navbar-collapse for grouping and hiding navbar contents by a parent breakpoint.
Add an optional .navbar-scroll to set a max-height and scroll expanded navbar content.

Here’s an example of all the sub-components included in a responsive dark-themed navbar that automatically collapses at the lg (large) breakpoint.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse align-items-end" id="navbarSupportedContent">
      <ul class="navbar-nav me-auto">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Dropdown
          </a>
          <ul class="dropdown-menu">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex navbar-item ms-3" role="search">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-primary" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

This example uses background (bg-dark) and spacing (me-auto, me-2, ms-3) utility classes.

Brand

The .navbar-brand can be used to contain most elements, but an anchor works best, as some elements might require utility classes or custom styles.

html

<!-- As a link -->
<header>
  <nav class="navbar">
    <div class="container-fluid">
      <div class="navbar-brand">
        <a class="stretched-link" href="#">
          <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
        </a>
        <h1 class="title">Navbar</h1>
      </div>
    </div>
  </nav>
</header>

<!-- As a heading -->
<header class="mt-3">
  <nav class="navbar">
    <div class="container-fluid">
      <div class="navbar-brand">
        <span class="stretched-link">
          <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
        </span>
        <h1 class="title">Navbar</h1>
      </div>
    </div>
  </nav>
</header>

Nav

Navbar navigation links build on our .nav options with their own modifier class and require the use of toggler classes for proper responsive styling. Navigation in navbars will also grow to occupy as much horizontal space as possible to keep your navbar contents securely aligned.

Add the .active class on .nav-link to indicate the current page.

Please note that you should also add the aria-current attribute on the active .nav-link.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" aria-disabled="true">Disabled</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

And because we use classes for our navs, you can avoid the list-based approach entirely if you like.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
      <div class="navbar-nav">
        <a class="nav-link active" aria-current="page" href="#">Home</a>
        <a class="nav-link" href="#">Features</a>
        <a class="nav-link" href="#">Pricing</a>
        <a class="nav-link disabled" aria-disabled="true">Disabled</a>
      </div>
    </div>
  </div>
</nav>

You can also use dropdowns in your navbar. Dropdown menus require a wrapping element for positioning, so be sure to use separate and nested elements for .nav-item and .nav-link as shown below.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavDropdown">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Dropdown link
          </a>
          <ul class="dropdown-menu">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </div>
</nav>

Forms

Place various form controls and components within a navbar:

html

<nav class="navbar">
  <div class="container-fluid">
    <form class="d-flex" role="search">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-primary" type="submit">Search</button>
    </form>
  </div>
</nav>

Immediate child elements of .navbar use flex layout. Use additional flex utilities as needed to adjust this behavior.

html

<nav class="navbar">
  <div class="container-fluid">
    <div class="navbar-brand me-auto">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
    <form class="d-flex navbar-item" role="search">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-primary" type="submit">Search</button>
    </form>
  </div>
</nav>

Input groups work, too. If your navbar is an entire form, or mostly a form, you can use the <form> element as the container and save some HTML. Applies to the option above and below this copy.

html

<nav class="navbar">
  <form class="container-fluid">
    <div class="input-group">
      <span class="input-group-text" id="basic-addon1">@</span>
      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
    </div>
  </form>
</nav>

Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.

html

<nav class="navbar">
  <form class="container-fluid justify-content-start align-items-center">
    <button class="btn btn-primary me-2" type="button">Main button</button>
    <button class="btn btn-sm btn-primary" type="button">Smaller button</button>
  </form>
</nav>

Text

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

html

<nav class="navbar">
  <div class="container-fluid">
    <span class="navbar-text">
      Navbar text with an inline element
    </span>
  </div>
</nav>

Mix and match with other components and utilities as needed.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse align-items-end" id="navbarText">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      <span class="navbar-text ms-3">
        Navbar text with an inline element
      </span>
    </div>
  </div>
</nav>

Color schemes

New dark navbars in v5.3.3 — We’ve deprecated .navbar-dark in favor of the new data-bs-theme="dark". Add data-bs-theme="dark" to the .navbar to enable a component-specific color mode. Learn more about our color modes.

New in v5.2.0 — Navbar theming is now powered by CSS variables and .navbar-light has been deprecated. CSS variables are applied to .navbar, defaulting to the “light” appearance, and can be overridden with .navbar-dark.

Navbar themes are easier than ever thanks to Bootstrap’s combination of Sass and CSS variables. The default is our “light navbar” for use with light background colors, but you can also apply data-bs-theme="dark" to the .navbar parent for dark background colors. Then, customize with .bg-* and additional utilities.

<nav class="navbar navbar-expand-lg bg-dark" data-bs-theme="dark">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-expand-lg bg-body-secondary">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-expand-lg" style="background-color: #e3f2fd;" data-bs-theme="light">
  <!-- Navbar content -->
</nav>

Containers

Although it’s not required, you can wrap a navbar in a .container to center it on a page–though note that an inner container is still required. Or you can add a container inside the .navbar to only center the contents of a fixed or static top navbar.

html

<div class="container">
  <nav class="navbar navbar-expand-lg">
    <div class="container-fluid">
      <div class="navbar-brand">
        <a class="stretched-link" href="#">
          <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
        </a>
      </div>
    </div>
  </nav>
</div>

Use any of the responsive containers to change how wide the content in your navbar is presented.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-md">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
    </div>
  </div>
</nav>

Placement

Use our position utilities to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, stickied to the top (scrolls with the page until it reaches the top, then stays there), or stickied to the bottom (scrolls with the page until it reaches the bottom, then stays there).

Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top on the <body>) to prevent overlap with other elements.

html

<nav class="navbar">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
      <h1 class="title">Default</h1>
    </div>
  </div>
</nav>

html

<nav class="navbar fixed-top">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
      <h1 class="title">Fixed top</h1>
    </div>
  </div>
</nav>

html

<nav class="navbar fixed-bottom">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
      <h1 class="title">Fixed bottom</h1>
    </div>
  </div>
</nav>

html

<nav class="navbar sticky-top">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
      <h1 class="title">Sticky top</h1>
    </div>
  </div>
</nav>

html

<nav class="navbar sticky-bottom">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
      <h1 class="title">Sticky bottom</h1>
    </div>
  </div>
</nav>

Scrolling

Add .navbar-nav-scroll to a .navbar-nav (or other navbar sub-component) to enable vertical scrolling within the toggleable contents of a collapsed navbar. By default, scrolling kicks in at 75vh (or 75% of the viewport height), but you can override that with the local CSS custom property --bs-navbar-height or custom styles. At larger viewports when the navbar is expanded, content will appear as it does in a default navbar.

Please note that this behavior comes with a potential drawback of overflow—when setting overflow-y: auto (required to scroll the content here), overflow-x is the equivalent of auto, which will crop some horizontal content.

Here’s an example navbar using .navbar-nav-scroll with style="--bs-scroll-height: 100px;", with some extra margin utilities for optimum spacing.

html

<nav class="navbar navbar-expand-lg">
  <div class="container-fluid">
    <div class="navbar-brand">
      <a class="stretched-link" href="#">
        <img src="/docs/5.3/assets/brand/orange-logo.svg" width="50" height="50" alt="Boosted - Back to Home" loading="lazy">
      </a>
      <h1 class="title">Scroll</h1>
    </div>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarScroll" aria-controls="navbarScroll" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse align-items-end" id="navbarScroll">
      <ul class="navbar-nav me-auto my-2 my-lg-0 navbar-nav-scroll align-items-end" style="--bs-scroll-height: 100px;">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Link
          </a>
          <ul class="dropdown-menu">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
      </ul>
      <form class="d-flex navbar-item ms-3 mt-md-4" role="search">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-primary" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

Responsive behaviors

Navbars can use .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl|-xxl} classes to determine when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.

External content

Sometimes you want to use the collapse plugin to trigger a container element for content that structurally sits outside of the .navbar . Because our plugin works on the id and data-bs-target matching, that’s easily done!

Collapsed content

Toggleable via the navbar brand.

html

<div class="collapse" id="navbarToggleExternalContent" data-bs-theme="dark">
  <div class="bg-dark p-4">
    <h5 class="text-body-emphasis h4">Collapsed content</h5>
    <span class="text-body-secondary">Toggleable via the navbar brand.</span>
  </div>
</div>
<nav class="navbar" data-bs-theme="dark">
  <div class="container-fluid">
    <button class="navbar-toggler ms-auto" type="button" data-bs-toggle="collapse" data-bs-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>

When you do this, we recommend including additional JavaScript to move the focus programmatically to the container when it is opened. Otherwise, keyboard users and users of assistive technologies will likely have a hard time finding the newly revealed content - particularly if the container that was opened comes before the toggler in the document’s structure. We also recommend making sure that the toggler has the aria-controls attribute, pointing to the id of the content container. In theory, this allows assistive technology users to jump directly from the toggler to the container it controls–but support for this is currently quite patchy.

Offcanvas

Transform your expanding and collapsing navbar into an offcanvas drawer with the offcanvas component. We extend both the offcanvas default styles and use our .navbar-expand-* classes to create a dynamic and flexible navigation sidebar.

In the example below, to create an offcanvas navbar that is always collapsed across all breakpoints, omit the .navbar-expand-* class entirely.

html

<nav class="navbar fixed-top">
  <div class="container-fluid">
    <button class="navbar-toggler ms-auto" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasNavbar" aria-controls="offcanvasNavbar" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

To create an offcanvas navbar that expands into a normal navbar at a specific breakpoint like lg, use .navbar-expand-lg.

<nav class="navbar navbar-expand-lg fixed-top">
  <button class="navbar-toggler ms-auto" type="button" data-bs-toggle="offcanvas" data-bs-target="#navbarOffcanvasLg" aria-controls="navbarOffcanvasLg" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="offcanvas offcanvas-end" tabindex="-1" id="navbarOffcanvasLg" aria-labelledby="navbarOffcanvasLgLabel">
    ...
  </div>
</nav>

When using offcanvas in a dark navbar, be aware that you may need to have a dark background on the offcanvas content to avoid the text becoming illegible. In the example below, we add [data-bs-theme="dark"] to the .navbar for proper styling with a dark offcanvas.

html

<nav class="navbar fixed-top" data-bs-theme="dark">
  <div class="container-fluid">
    <button class="navbar-toggler ms-auto" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasDarkNavbar" aria-controls="offcanvasDarkNavbar" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="offcanvas offcanvas-end" tabindex="-1" id="offcanvasDarkNavbar" aria-labelledby="offcanvasDarkNavbarLabel">
      <div class="offcanvas-header">
        <h5 class="offcanvas-title" id="offcanvasDarkNavbarLabel">Dark offcanvas</h5>
        <button type="button" class="btn-close" data-bs-dismiss="offcanvas" aria-label="Close" data-bs-toggle="tooltip" data-bs-placement="bottom" data-bs-title="Close"></button>
      </div>
      <div class="offcanvas-body">
        <ul class="navbar-nav justify-content-end flex-grow-1 pe-3">
          <li class="nav-item">
            <a class="nav-link active" aria-current="page" href="#">Home</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#">Link</a>

Tooltips on close buttons of offcanvases navbars have to be initialized. Tooltips can be initialized globally in the project.

CSS

Variables

Added in v5.2.0

As part Boosted’s evolving CSS variables approach, navbars now use local CSS variables on .navbar for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

scss/_navbar.scss

--#{$prefix}navbar-padding-x: #{if($navbar-padding-x == null, 0, $navbar-padding-x)};
--#{$prefix}navbar-padding-y: 0; // Boosted mod: no padding in small breakpoints

--#{$prefix}navbar-border-width: #{$navbar-border-width}; // Boosted mod

Some additional CSS variables are also present on .navbar-nav:

scss/_navbar.scss

--#{$prefix}nav-link-padding-x: var(--#{$prefix}navbar-nav-link-padding-x); // Boosted mod
--#{$prefix}nav-link-padding-y: var(--#{$prefix}navbar-nav-link-padding-y); // Boosted mod

Sass loops

Responsive navbar expand/collapse classes (e.g., .navbar-expand-lg) are combined with the $breakpoints map and generated through a loop in scss/_navbar.scss.

scss/_navbar.scss

// Generate series of `.navbar-expand-*` responsive classes for configuring
// where your navbar collapses.
.navbar-expand {
  @each $breakpoint in map-keys($grid-breakpoints) {
    $next: breakpoint-next($breakpoint, $grid-breakpoints);
    $infix: breakpoint-infix($next, $grid-breakpoints);

    // stylelint-disable-next-line scss/selector-no-union-class-name
    &#{$infix} {
      @include media-breakpoint-up($next) {
        flex-wrap: nowrap;
        justify-content: flex-start;

              background-color: currentcolor;
              @include transition($navbar-active-transition);
            }
          }

          .nav-item {
