<h3>Bootstrap 3 Grid Medium</h3>
<p>In Bootstrap 3, the grid system allows you to create responsive layouts using a series of containers, rows, and columns. The "medium" grid class is specifically used to define how columns behave on medium devices (&ge;768px).</p>
<h4>Medium Device Grid Classes</h4>
<ul>
<li><code>.col-md-*</code>: This class specifies how many columns an element should take up on medium devices (&ge;768px).</li>
<li>Medium devices typically include tablets in landscape mode and small laptops.</li>
</ul>
<h3>Example of Bootstrap 3 Grid Medium</h3>
<p>Here&rsquo;s a detailed example demonstrating how to use the grid system for medium devices:</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;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class="container"&gt;
    &lt;h2&gt;Bootstrap 3 Grid Medium Example&lt;/h2&gt;
    
    &lt;div class="row"&gt;
        &lt;div class="col-xs-12 col-sm-6 col-md-4"&gt;
            &lt;div class="well"&gt;Column 1: Medium (4) | Small (6) | Extra Small (12)&lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="col-xs-12 col-sm-6 col-md-4"&gt;
            &lt;div class="well"&gt;Column 2: Medium (4) | Small (6) | Extra Small (12)&lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="col-xs-12 col-sm-6 col-md-4"&gt;
            &lt;div class="well"&gt;Column 3: Medium (4) | Small (6) | Extra Small (12)&lt;/div&gt;
        &lt;/div&gt;
    &lt;/div&gt;
    
    &lt;div class="row"&gt;
        &lt;div class="col-xs-12 col-md-6"&gt;
            &lt;div class="well"&gt;Column 4: Medium (6) | Extra Small (12)&lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="col-xs-12 col-md-6"&gt;
            &lt;div class="well"&gt;Column 5: Medium (6) | Extra Small (12)&lt;/div&gt;
        &lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;

&lt;!-- Include jQuery and Bootstrap JS --&gt;
&lt;script src="https://code.jquery.com/jquery-1.11.1.min.js"&gt;&lt;/script&gt;
&lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"&gt;&lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;

<h3>Explanation of the Grid Medium Example Code</h3>
<ol>
<li><strong>Container</strong>: The <code>.container</code> class creates a responsive fixed-width container.</li>
<li><strong>Rows</strong>: Each <code>.row</code> class creates a horizontal group for the columns.</li>
<li><strong>Columns</strong>:
<ul>
<li>The first row has three columns that take up 4 columns each on medium devices (33.33% width), 6 columns each on small devices (50% width), and 12 columns each on extra small devices (100% width).</li>
<li>The second row has two columns that take up 6 columns each on medium devices (50% width) and 12 columns each on extra small devices (100% width).</li>
</ul>
</li>
</ol>
<h3>Responsive Behavior</h3>
<ul>
<li><strong>Extra Small Devices</strong>: On screens smaller than 768px, each column takes the full width of the container (<code>col-xs-12</code>).</li>
<li><strong>Small Devices</strong>: On screens 768px and larger, the columns will adjust to take up 50% of the width (<code>col-sm-6</code>).</li>
<li><strong>Medium Devices</strong>: On screens 992px and larger, the columns will adjust to take up 33.33% of the width (<code>col-md-4</code>) or 50% width for the second row.</li>
</ul>
