<h1>Bootstrap 4 Modal</h1>
<h2>Overview</h2>
<p>A modal in Bootstrap 4 is built using HTML, CSS, and JavaScript, allowing you to create overlay dialogs that can contain any type of content. The modal is activated by clicking a button or link, and it can be easily customized for various use cases.</p>
<h2>Basic Modal Structure</h2>
<h3>Example: Simple Modal</h3>
<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;!-- Button to Open Modal --&gt;
&lt;button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"&gt;
    Launch Demo Modal
&lt;/button&gt;

&lt;!-- Modal Structure --&gt;
&lt;div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"&gt;
    &lt;div class="modal-dialog" role="document"&gt;
        &lt;div class="modal-content"&gt;
            &lt;div class="modal-header"&gt;
                &lt;h5 class="modal-title" id="exampleModalLabel"&gt;Modal title&lt;/h5&gt;
                &lt;button type="button" class="close" data-dismiss="modal" aria-label="Close"&gt;
                    &lt;span aria-hidden="true"&gt;&amp;times;&lt;/span&gt;
                &lt;/button&gt;
            &lt;/div&gt;
            &lt;div class="modal-body"&gt;
                This is the modal body content.
            &lt;/div&gt;
            &lt;div class="modal-footer"&gt;
                &lt;button type="button" class="btn btn-secondary" data-dismiss="modal"&gt;Close&lt;/button&gt;
                &lt;button type="button" class="btn btn-primary"&gt;Save changes&lt;/button&gt;
            &lt;/div&gt;
        &lt;/div&gt;
