##### Light navbar

Light navbar is a basic Bootstrap navbar with white background color defined in `$navbar-light-bg` variable. Light navbar is the only navbar style that has light color scheme. By default, basic Bootstrap styling has only 2 color presets: `light` and `dark`. To use light navbar styling, add `.navbar-light` class to the base `.navbar` container, styles of all navbar components will be adjusted to the light background theme automatically.

Light navbar example:

Light navbar markup:

    <!-- Light navbar -->
    <div class="navbar navbar-light navbar-expand-md">

    	<!-- Navbar brand -->
    	<div class="navbar-brand">
    		...
    	</div>
    	<!-- /navbar brand -->

    	<!-- Mobile toggler -->
    	<div class="d-md-none">
    		...
    	</div>
    	<!-- /mobile toggler -->

    	<!-- Navbar content -->
    	<div class="collapse navbar-collapse" id="navbar-main">
    		...
    	</div>
    	<!-- /navbar content -->

    </div>
    <!-- /light navbar -->

##### Dark navbar

Dark navbar is one of the default Bootstrap navbar styles with `dark` blue/grey background color defined in `$navbar-dark-bg` variable. Default BS styling requires color helper class added to `.navbar-dark` container. This behaviour was improved and all `.bg-[color]` classes are now optional, but still require `.navbar-dark` class for proper content styling. Some elements require minor color adjustments (link and border colors), so use utility classes to make them pixel perfect.

Dark navbar example:

Dark navbar markup:

    <!-- Dark navbar -->
    <div class="navbar navbar-dark navbar-expand-md">

    	<!-- Navbar brand -->
    	<div class="navbar-brand">
    		...
    	</div>
    	<!-- /navbar brand -->

    	<!-- Mobile toggler -->
    	<div class="d-md-none">
    		...
    	</div>
    	<!-- /mobile toggler -->

    	<!-- Navbar content -->
    	<div class="collapse navbar-collapse" id="navbar-main">
    		...
    	</div>
    	<!-- /navbar content -->

    </div>
    <!-- /dark navbar -->

##### Custom navbar color

Both light and dark navbars support custom background colors from template's color system and default BS color options. For custom colors use `.bg-[color]`All components inside navbar automatically adjust text, placeholder and background colors according to the specified color theme.

Custom background color example:

Custom dark color markup:

    <!-- Custom dark color -->
    <div class="navbar navbar-dark bg-blue navbar-expand-md">

    	<!-- Navbar brand -->
    	<div class="navbar-brand">
    		...
    	</div>
    	<!-- /navbar brand -->

    	<!-- Mobile toggler -->
    	<div class="d-md-none">
    		...
    	</div>
    	<!-- /mobile toggler -->

    	<!-- Navbar content -->
    	<div class="collapse navbar-collapse" id="navbar-main">
    		...
    	</div>
    	<!-- /navbar content -->

    </div>
    <!-- /custom dark color -->

##### Color combinations

Background colors in multiple navbars can be mixed: you can specify custom background colors for `main` and `secondary` navbars or make them look identical. All navbars have top and bottom borders, so in some color combinations you might need to use `border` utility classes to remove some borders, change border color or make them transparent (prefered for correct padding calculations in SASS).

Example of mixing dark colors:

Multiple navbars markup:

    <!-- First navbar -->
    <div class="navbar navbar-dark bg-teal-400 navbar-expand-md">

    	<!-- Navbar content -->
    	<div class="navbar-brand">
    		...
    	</div>
    	<div class="d-md-none">
    		...
    	</div>
    	<div class="collapse navbar-collapse" id="navbar-first">
    		...
    	</div>
    	<!-- /navbar content -->

    </div>
    <!-- /first navbar -->

    <!-- Second navbar -->
    <div class="navbar navbar-dark bg-slate-700 navbar-expand-md">

    	<!-- Navbar content -->
    	<div class="navbar-brand">
    		...
    	</div>
    	<div class="d-md-none">
    		...
    	</div>
    	<div class="collapse navbar-collapse" id="navbar-second">
    		...
    	</div>
    	<!-- /navbar content -->

    </div>
    <!-- /second navbar -->

##### Navbar classes

Navbar is a complex, but very flexible component. It supports different types of content, responsive utilities manage content appearance and spacing on various screen sizes, supports multiple sizing and color options etc. And everything can be changed on-the-fly directly in HTML markup. If you can't find an option you need, you can always extend default SCSS code. Table below demonstrates all available classes that can be used within the navbar:

Class | Type | Description
--- | --- | ---
`.navbar` | Required | Default navbar class, must be used with any navbar type and color. Responsible for basic navbar and navbar components styling as a parent container.
`.navbar-light` | Required | This class is used for `dark` background colors - default dark color is set in `$navbar-light-bg` variable, feel free to adjust the color according to your needs.
`.navbar-light.alpha-*` | Optional | Combination of these classes allows you to set custom light color to the `light` navbar. Note - `.navbar-light` is required, it's responsible for correct content styling.
`.navbar-dark` | Required | This class is used for `dark` background colors - default dark color is set in `$navbar-dark-bg` variable, feel free to adjust the color according to your needs.
`.navbar-dark.bg-*` | Optional | Combination of these classes allows you to set custom dark color to the `dark` navbar. Note - `.navbar-dark` is required, it's responsible for correct content styling.
`.navbar-expand-[breakpoint]` | Optional | 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. Otherwise use this class to change when navbar content collapses behind a button.
`.navbar-brand` | Required | Class for logo container. It can be applied to most elements, but an anchor works best as some elements might require utility classes or custom styles
`.navbar-toggler` | Required | This class needs to be added to the navbar toggle button that toggles navbar content on small screens. Always used with visibility utility classes.
`.navbar-collapse` | Required | Groups and hides navbar contents by a parent breakpoint. Requires an ID for targeting collapsible container when sidebar content is collapsed.
`.navbar-nav` | Required | Responsive navigation container class that adds default styling for navbar navigation.
`.nav-item` | Required | Wrapper class for immediate parents of all navigation links. Responsible for correct styling of nav items
`.navbar-nav-link` | Required | Custom class for links within `.navbar-nav` list, it sets proper styling for links in light and dark navbars.
`.navbar-text` | Required | This class adjusts vertical alignment and horizontal spacing for strings of text
`.navbar-component` | Optional | Display navbar as a stand alone component, with border and rounded corners.
`.fixed-top` | Optional | Makes navbar sticked to the `top` of the page. Requires proper class for `<body>` container, see the table below.
`.fixed-bottom` | Optional | Makes navbar sticked to the `bottom` of the page. Requires proper class for `<body>` container, see the table below.
`.sticky-top` | Optional | Adds `position: sticky;` to the navbar - it's treated as relatively positioned until its containing block crosses a specified threshold, at which point it is treated as fixed. Support is limited.

##### Body classes

If you want to place navbar in non-static positions, you can choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use `position: fixed`, meaning they’re pulled from the normal flow of the DOM and require custom classes added to the `<body>` container to prevent overlap with other elements. The following table demonstrates the list of classes for `<body>` container if navbar has non-static position:

Class | Description
--- | ---
`.navbar-top` | This class adds `top` padding to the `<body>` container. Works only with default navbar height. If another height is specified, apply another class (see the line below).
`.navbar-bottom` | This class adds `bottom` padding to the `<body>` container. Works only with default navbar height. If another height is specified, apply another class (see the line below).
`.navbar-top-[size]` | Controls `top` spacing of `<body>` container, if navbar has optional height. Available sizes: small (`*-sm`) and large (`*-lg`). Default navbar requires `.navbar-top` class only.
`.navbar-bottom-[size]` | Controls `bottom` spacing of `<body>` container, if navbar has optional height. Available sizes: small (`*-sm`) and large (`*-lg`). Default navbar requires `.navbar-bottom` class only.
`.navbar-top-[size]-[size]` | Use these classes if the layout has multiple `top` navbars, where first `[size]` is the size of the first navbar, second `[size]` - height of the second navbar. In this particular use case, `[size]` can be: `lg` if large height, `md` is default height `sm` is small height.
`.navbar-bottom-[size]-[size]` | Use these classes if the layout has multiple `bottom` navbars, where first `[size]` is the size of the first navbar, second `[size]` - height of the second navbar. In this particular use case, `[size]` can be: `lg` if large height, `md` is default height `sm` is small height.
