<h3>Bootstrap 3 Navbar</h3>
<p>The <strong>Navbar</strong> in Bootstrap 3 is a flexible and powerful component for creating responsive navigation headers for your web applications. It helps to provide a consistent user interface and enhances the usability of your website.</p>
<hr />
<h3>Basic Usage of Navbar</h3>
<p>You can create a simple navigation bar using the <code>.navbar</code>, <code>.navbar-default</code>, and <code>.navbar-header</code> classes. The navbar can contain brand logos, links, and collapsible components.</p>
<h4>Example of a Basic Navbar</h4>
<div class="contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative bg-token-sidebar-surface-primary dark:bg-gray-950">
<div class="flex items-center text-token-text-secondary px-4 py-2 text-xs font-sans justify-between rounded-t-md h-9 bg-token-sidebar-surface-primary dark:bg-token-main-surface-secondary">html</div>
<div class="sticky top-9 md:top-[5.75rem]">
<div class="absolute bottom-0 right-2 flex h-9 items-center">
<div class="flex items-center rounded bg-token-sidebar-surface-primary px-2 font-sans text-xs text-token-text-secondary dark:bg-token-main-surface-secondary">
<pre class="language-markup"><code>&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;
&lt;head&gt;
    &lt;meta charset="UTF-8"&gt;
    &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
    &lt;title&gt;Bootstrap 3 Navbar Example&lt;/title&gt;
    &lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;nav class="navbar navbar-default"&gt;
    &lt;div class="container-fluid"&gt;
        &lt;!-- Brand and toggle get grouped for better mobile display --&gt;
        &lt;div class="navbar-header"&gt;
            &lt;button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse-1" aria-expanded="false"&gt;
                &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&gt;
                &lt;span class="icon-bar"&gt;&lt;/span&gt;
                &lt;span class="icon-bar"&gt;&lt;/span&gt;
                &lt;span class="icon-bar"&gt;&lt;/span&gt;
            &lt;/button&gt;
            &lt;a class="navbar-brand" href="#"&gt;My Website&lt;/a&gt;
        &lt;/div&gt;

&lt;!-- Collect the nav links for toggling --&gt;
        &lt;div class="collapse navbar-collapse" id="navbar-collapse-1"&gt;
            &lt;ul class="nav navbar-nav"&gt;
                &lt;li class="active"&gt;&lt;a href="#"&gt;Home&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a href="#"&gt;About&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a href="#"&gt;Services&lt;/a&gt;&lt;/li&gt;
                &lt;li&gt;&lt;a href="#"&gt;Contact&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
        &lt;/div&gt;&lt;!-- /.navbar-collapse --&gt;
    &lt;/div&gt;&lt;!-- /.container-fluid --&gt;
&lt;/nav&gt;

&lt;div class="container"&gt;
    &lt;h2&gt;Welcome to My Website&lt;/h2&gt;
    &lt;p&gt;This is an example of a Bootstrap 3 navbar.&lt;/p&gt;
&lt;/div&gt;

&lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"&gt;&lt;/script&gt;
