Navbar

Create responsive navigation header, the navbar which includes support for branding, navigation, forms and more, including support for collapse plugin.

• Navbars require a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl} for responsive collapsing and color scheme classes.
• Navbars and their contents are fluid by default. Use optional containers to limit their horizontal width.
• 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.
• Navbars are hidden by default when printing. Force them to be printed by adding .d-print to the .navbar. See the display utility class.
• 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.

You can add below sub-components within a navbar.

• .navbar-brand for your company, 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 togglingbehaviors.
• .form-inline 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.

The below example uses light-themed (bg-light) navbar and for spacing uses utility classes(my-2, my-lg-0, mr-sm-0, my-sm-0) that automatically collapses at the lg (large) breakpoint.

Add your site name(brand) inside a anchor with .navbar-brand class. .navbar-brand can be applied to most elements other than anchor, but other elements might require some utility classes or custom styles.

Adding images to the .navbar-brand. You might require custom styles or utilities size properly.

Create navbar navigation links .navbar-nav on the unordered list. It 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 aligned properly.

Indicate active states with .active for the current page which can be applied directly to .nav-links or their immediate parent .nav-items.

You can also create navbar without using unordered list.

Dropdown menus require a wrapping element for positioning. So use separate and nested elements for .nav-item and .nav-link.

Place various form controls and components within a navbar with .form-inline.

Immediate children elements in .navbar use flex layout and will default to justify-content: between. Use flex utilities as needed to adjust this behavior.

Input groups also work with navbar.

You can also add buttons as part of these navbar forms.

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

Below example contains few components and utilities.

Navbar can be colored using theming classes and background-color utilities. Choose from .navbar-light for use with light background colors, or .navbar-dark for dark background colors. Then, customize with .bg-* utilities. You could also use custom inline-styles or css for background colors.

You can wrap a navbar in a .container to center it on a page or add one within to only center the contents of a fixed or static top navbar.

When the container is within your navbar, its horizontal padding is removed at breakpoints lower than your specified .navbar-expand{-sm|-md|-lg|-xl} class. This removes unnecessarily doubling up on padding on lower viewports when your navbar is collapsed.

Place the navbar using position utilities as needed. It supports .fixed-top(fixed to the top), .fixed-bottom(fixed to the bottom), or .sticky-top(sticked to the top) (scrolls with the page until it reaches the top, then stays there).

Fixed navbars use position: fixed which may require custom CSS (e.g., padding-top on the <body>) to prevent overlap with other elements.

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

• 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.

By default navbar togglers are left-aligned, but should they follow a sibling element like a .navbar-brand, they'll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler.

With no .navbar-brand shown in lowest breakpoint.

With a brand name shown on the left and toggler on the right

With a toggler on the left and brand name on the right:

You want to use the collapse plugin to trigger hidden content elsewhere on the page. Because plugin works on the id and matching data-target
