-### Basics
+## Basics

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

- Navbars require a wrapping `.navbar` and either a color scheme class or custom styles.
+- Navbars require a wrapping `.navbar` and a color scheme class (either `.navbar-default` or `.navbar-inverse`).
 - When using multiple components in a navbar, some [alignment classes](#alignment) are required.
 - Navbars and their contents are fluid by default. Use [optional containers](#containers) to limit their horizontal width.
+- Use `.pull-left` and `.pull-right` to quickly align sub-components.
 - 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.

-### Branding
+## Supported content

-Name your company, product, or project with `.navbar-brand`.
+Navbars come with built-in support for a handful of sub-components. Mix and match from the following as you need:
+
+- `.navbar-brand` for your company, product, or project name
+- `.navbar-nav` for a full-height and lightweight navigation (including support for dropdowns)
+- `.navbar-form` for vertically centering default-sized inputs and buttons.
+- `.navbar-toggler` for use with our collapse plugin and other navigation toggling behaviors.
+
+Here's an example of all the sub-components included in a default, light navbar:

 {% example html %}
-<nav class="navbar navbar-default">
-  <h3 class="navbar-brand">
-    <a href="#">Navbar</a>
-  </h3>
-</nav>
-{% endexample %}

-### Navigation
-
-Use `.nav-pills` within a navbar for basic navigation.

-{% endexample %}

-### Inline forms
-
-Add an `.inline-form` within the navbar with nearly any combination of form controls and buttons.
-
-{% example html %}
-<nav class="navbar navbar-default">
-  <form class="form-inline">
+  <form class="form-inline navbar-form pull-right">

  </form>
 </nav>
 {% endexample %}

-### Containers
+## Color schemes

-Although it's not required, you can wrap a navbar in a `.container` to center it on a page, or add one within to only center the contents of the navbar.
+Theming the navbar has never been easier thanks to the combination of a simple link color modifier class and `background-color` utilities. Put another way, you specify light or dark and apply a background color.

-### Alignment
-
-Use `.pull-left` or `.pull-right` to align multiple elements within the navbar.

-### Small navbar
-
-Small navbars provide a similar aesthetic to Bootstrap 3's navbar. It cuts the padding down, enables full-height navigation, and tweaks vertical alignment for search forms, buttons, and more. It's also available in both default and inverse schemes.
-
-When moving from a regular navbar to a small one, be sure to update your inputs and buttons to use their small variations as well.
+Here are some examples to show what we mean.

 <div class="bd-example">
-  <nav class="navbar navbar-default navbar-sm">

-### Collapsible content
+## Containers
+
+Although it's not required, you can wrap a navbar in a `.container` to center it on a page or add one within to only center the contents of the navbar.
+
+{% example html %}
+<div class="container">
+  <nav class="navbar navbar-light bg-faded">
+    <a class="navbar-brand" href="#">Navbar</a>
+  </nav>

+    <a class="navbar-brand" href="#">Navbar</a>
+  </div>
+</nav>
+{% endexample %}
+
+## Placement
+
+Navbars can be statically placed (their default behavior), or fixed to the top or bottom of the viewport.
+
+{% example html %}
+<nav class="navbar navbar-fixed-top navbar-light bg-faded">
+  <a class="navbar-brand" href="#">Fixed top</a>
+</nav>
+{% endexample %}

 Our collapse plugin allows you to use a `<button>` or `<a>` to toggle hidden content.

 For more complex navbar patterns, like those used in Bootstrap v3, use the `.navbar-toggleable-*` classes in conjunction with the `.navbar-toggler`. These classes override our responsive utilities to show navigation only when content is meant to be shown.

 ### Responsive utilities

-The following deprecated Less/SCSS variables have been removed in v4.0.0:
+The following deprecated variables have been removed in v4.0.0:

 * `@screen-phone`, `@screen-tablet`, `@screen-desktop`, `@screen-lg-desktop`. Use the more abstract `$screen-{xs,sm,md,lg,xl}-*` variables instead.
 * `@screen-sm`, `@screen-md`, `@screen-lg`. Use the more clearly named `$screen-{xs,sm,md,lg,xl}-min` variables instead.
 * `@screen-xs`, `@screen-xs-min`. The extra small breakpoint has no lower bound, so these variables were logically absurd. Reformulate your expression in terms of `$screen-xs-max` instead.
-* `@grid-float-breakpoint`

-The responsive utility classes have been overhauled. The old classes (`.hidden-xs` `.hidden-sm` `.hidden-md` `.hidden-lg` `.visible-xs-block` `.visible-xs-inline` `.visible-xs-inline-block` `.visible-sm-block` `.visible-sm-inline` `.visible-sm-inline-block` `.visible-md-block` `.visible-md-inline` `.visible-md-inline-block` `.visible-lg-block` `.visible-lg-inline` `.visible-lg-inline-block`) are gone. They have been replaced by `.hidden-xs-up` `.hidden-xs-down` `.hidden-sm-up` `.hidden-sm-down` `.hidden-md-up` `.hidden-md-down` `.hidden-lg-up` `.hidden-lg-down`. The `.hidden-*-up` classes hide the element when the viewport is at the given breakpoint or wider (e.g. `.hidden-md-up` hides an element on medium, large, and extra-large devices). The `.hidden-*-down` classes hide the element when the viewport is at the given breakpoint or smaller (e.g. `.hidden-md-down` hides an element on extra-small, small, and medium devices). Rather than using explicit `.visible-*` classes, you make an element visible by simply not hiding it at that screen size. You can combine one `.hidden-*-up` class with one `.hidden-*-down` class to show an element only on a given interval of screen sizes (e.g. `.hidden-sm-down.hidden-xl-up` shows the element only on medium and large devices). Note that the changes to the grid breakpoints in v4 means that you'll need to go one breakpoint larger to achieve the same results (e.g. `.hidden-md` is more similar to `.hidden-lg-down` than to `.hidden-md-down`). .The new responsive utility classes don't attempt to accommodate less common cases where an element's visibility can't be expressed as a single contiguous range of viewport sizes; you will instead need to use custom CSS in such cases.
