<h3>Bootstrap 5: Containers</h3>
<p>In Bootstrap 5, <strong>containers</strong> are fundamental building blocks used to create a responsive layout. They provide a way to align content within the viewport while allowing for various responsive behaviors. Bootstrap 5 offers three types of containers:</p>
<ol>
<li><strong>.container</strong>: A responsive fixed-width container.</li>
<li><strong>.container-fluid</strong>: A full-width container that spans the entire width of the viewport.</li>
<li><strong>.container-{breakpoint}</strong>: A responsive container that changes its width based on the specified breakpoint.</li>
</ol>
<hr />
<h3>Types of Containers</h3>
<h4>1. Fixed Container (<code>.container</code>)</h4>
<p>The fixed-width container adjusts its width based on the screen size, with defined maximum widths at different breakpoints.</p>
<p><strong>Example:</strong></p>
<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;div class="container"&gt;
    &lt;h1&gt;Fixed Container&lt;/h1&gt;
    &lt;p&gt;This container has a fixed width and is centered within the viewport.&lt;/p&gt;
&lt;/div&gt;
</code></pre>
</div>
</div>
</div>
</div>
<h4>2. Fluid Container (<code>.container-fluid</code>)</h4>
<p>The fluid container expands to fill the entire width of the viewport, regardless of the screen size.</p>
<p><strong>Example:</strong></p>
<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;div class="container-fluid"&gt;
    &lt;h1&gt;Fluid Container&lt;/h1&gt;
    &lt;p&gt;This container takes the full width of the screen.&lt;/p&gt;
&lt;/div&gt;
</code></pre>
</div>
</div>
</div>
</div>
<h4>3. Breakpoint-Specific Containers</h4>
<p>You can create containers that are responsive at specific breakpoints (e.g., <code>.container-sm</code>, <code>.container-md</code>, <code>.container-lg</code>, <code>.container-xl</code>, <code>.container-xxl</code>).</p>
<p><strong>Example:</strong></p>
<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;div class="container-lg"&gt;
    &lt;h1&gt;Large Container&lt;/h1&gt;
    &lt;p&gt;This container will be responsive and only take the full width at smaller breakpoints.&lt;/p&gt;
&lt;/div&gt;
</code></pre>
</div>
</div>
</div>
</div>

<h3>Example: Using Containers in Bootstrap 5</h3>
<p>Here&rsquo;s a simple example that demonstrates the use of different types of containers:</p>
<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=1.0"&gt;
    &lt;title&gt;Bootstrap 5 Containers&lt;/title&gt;
    &lt;link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet"&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;!-- Fixed Container --&gt;
    &lt;div class="container"&gt;
        &lt;h1&gt;Fixed Container&lt;/h1&gt;
        &lt;p&gt;This container adjusts its width based on the screen size.&lt;/p&gt;
    &lt;/div&gt;

&lt;!-- Fluid Container --&gt;
    &lt;div class="container-fluid bg-light"&gt;
        &lt;h1&gt;Fluid Container&lt;/h1&gt;
        &lt;p&gt;This container takes up the full width of the viewport.&lt;/p&gt;
    &lt;/div&gt;

&lt;!-- Large Container --&gt;
    &lt;div class="container-lg bg-secondary text-white"&gt;
        &lt;h1&gt;Large Container&lt;/h1&gt;
        &lt;p&gt;This container will be responsive at the larger breakpoint.&lt;/p&gt;
    &lt;/div&gt;

&lt;script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"&gt;&lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<h3>Explanation of the Code</h3>
<ul>
<li><strong>Fixed Container</strong>: The first container uses the <code>.container</code> class, adjusting its width based on the screen size.</li>
<li><strong>Fluid Container</strong>: The second container uses <code>.container-fluid</code>, which spans the full width of the viewport and has a light background for distinction.</li>
<li><strong>Large Container</strong>: The third container uses <code>.container-lg</code>, allowing it to be responsive at larger screen sizes, with a secondary background color and white text.</li>
</ul>
