<h3>Bootstrap 5 Grid: Small (SM) Layout</h3>
<p>Bootstrap 5's grid system enables developers to create responsive and flexible layouts by utilizing predefined grid classes. The "small" (<code>sm</code>) grid is designed specifically for screens that are 576 pixels wide and larger, allowing for more detailed control over your layout compared to extra small devices.</p>

<h3>Understanding the Small Grid System</h3>
<p>In Bootstrap 5, the <code>col-sm-*</code> classes are used to define the number of columns in a row when viewed on small screens. This ensures that columns align horizontally rather than stacking vertically.</p>
<p><strong>Basic Structure 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;div class="row"&gt;
        &lt;div class="col-sm-4"&gt;Column 1&lt;/div&gt;
        &lt;div class="col-sm-4"&gt;Column 2&lt;/div&gt;
        &lt;div class="col-sm-4"&gt;Column 3&lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>
</div>
</div>
</div>
</div>
<ul>
<li><strong>Below 576px</strong>: The columns will stack vertically, each taking the full width of the container.</li>
<li><strong>576px and above</strong>: The columns will display side by side, each taking one-third of the row width (<code>col-sm-4</code>).</li>
</ul>
<hr />
<h3>Example: Stacking and Horizontal Layout</h3>
<p>You can combine the <code>col</code> and <code>col-sm-*</code> classes to create a layout that adapts to different screen sizes:</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;div class="row"&gt;
        &lt;div class="col-12 col-sm-6"&gt;Column 1&lt;/div&gt;
        &lt;div class="col-12 col-sm-6"&gt;Column 2&lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>
</div>
</div>
</div>
</div>
<ul>
<li><strong>Under 576px</strong>: Columns stack vertically with full width (<code>col-12</code>).</li>
<li><strong>576px and above</strong>: Columns will align horizontally, each taking half of the width (<code>col-sm-6</code>).</li>
</ul>
<hr />
<h3>Combining Small with Other Breakpoints</h3>
<p>You can further customize the layout by combining small (<code>sm</code>) with other breakpoints like medium (<code>md</code>) and large (<code>lg</code>):</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;div class="row"&gt;
        &lt;div class="col-12 col-sm-4 col-md-3"&gt;Column 1&lt;/div&gt;
        &lt;div class="col-12 col-sm-4 col-md-3"&gt;Column 2&lt;/div&gt;
        &lt;div class="col-12 col-sm-4 col-md-3"&gt;Column 3&lt;/div&gt;
        &lt;div class="col-12 col-sm-4 col-md-3"&gt;Column 4&lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>
</div>
</div>
</div>
</div>
<ul>
<li><strong>Under 576px</strong>: Columns stack vertically at full width.</li>
<li><strong>576px and above</strong>: Four columns per row, each taking one-fourth of the width (<code>col-sm-4</code>).</li>
<li><strong>768px and above</strong>: Each column takes one-third of the row width (<code>col-md-3</code>).</li>
</ul>

<h3>Key Features of the Small Grid System</h3>
<ol>
<li><strong>Responsive Design</strong>: Automatically adapts to screen size, making it suitable for mobile-first design.</li>
<li><strong>Flexible Layouts</strong>: Easily combine with other grid classes for multi-breakpoint support.</li>
<li><strong>Ease of Use</strong>: Simplifies the process of creating complex layouts without extensive custom CSS.</li>
</ol>
