<h3><strong>B</strong>ootstrap 5: Tooltip</h3>
<p>Tooltips in Bootstrap 5 are small overlay components that provide additional information about an element when a user hovers over or focuses on it. They are perfect for enhancing user experience by offering context without cluttering the interface.</p>
<hr />
<h3>Key Features of Bootstrap 5 Tooltip</h3>
<ol>
<li><strong>Dynamic Positioning</strong>: Tooltips automatically position themselves based on the available screen space and the target element.</li>
<li><strong>Customizable Styles</strong>: You can easily customize the appearance using Bootstrap utility classes and custom CSS.</li>
<li><strong>Accessibility</strong>: Tooltips support accessibility by being keyboard navigable and readable by screen readers.</li>
<li><strong>JavaScript Control</strong>: Tooltips can be activated and deactivated via JavaScript for more complex behaviors.</li>
<li><strong>HTML Content</strong>: Tooltips can display not just text, but also HTML content for richer information.</li>
</ol>

<h3>Example: Creating a Tooltip in Bootstrap 5</h3>
<p>Here&rsquo;s a simple example demonstrating how to implement a tooltip using Bootstrap 5:</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 Tooltip Example&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;!-- Tooltip trigger --&gt;
    &lt;button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-placement="top" title="Tooltip on top"&gt;
        Hover me
    &lt;/button&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;script&gt;
        // Initialize all tooltips
        var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
        var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
            return new bootstrap.Tooltip(tooltipTriggerEl)
        })
    &lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<h3>Explanation of the Code</h3>
<ul>
<li><strong>Tooltip Trigger</strong>: The button has the <code>data-bs-toggle="tooltip"</code> attribute, which tells Bootstrap to enable a tooltip on this element. The <code>title</code> attribute holds the tooltip text, while <code>data-bs-placement</code> specifies its position (e.g., top, bottom, left, right).</li>
<li><strong>JavaScript Initialization</strong>: The script initializes the tooltip for all elements with the <code>data-bs-toggle="tooltip"</code> attribute. This must be done after loading the Bootstrap JavaScript library to ensure tooltips are functional.</li>
</ul>
