<h3>Bootstrap 4 JavaScript Tooltip</h3>
<p>Bootstrap 4&rsquo;s Tooltip component provides a way to display informative text when a user hovers over, focuses on, or taps an element. Tooltips are commonly used to provide context or additional information without taking up extra space in the UI.</p>
<hr />
<h3>1. Basic Tooltip Setup</h3>
<p>To add a tooltip, use the <code>data-toggle="tooltip"</code> attribute on an element, then specify the tooltip text with the <code>title</code> attribute. Ensure to initialize tooltips with JavaScript for them to function correctly.</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;!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 Tooltip Example&lt;/title&gt;
    &lt;!-- Bootstrap CSS CDN --&gt;
    &lt;link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class="container mt-5"&gt;
        &lt;!-- Tooltip Button --&gt;
        &lt;button type="button" class="btn btn-primary" data-toggle="tooltip" data-placement="top" title="Tooltip on top"&gt;
            Hover to see Tooltip
        &lt;/button&gt;
    &lt;/div&gt;

&lt;!-- Bootstrap JS and dependencies --&gt;
    &lt;script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"&gt;&lt;/script&gt;
    &lt;script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.2/dist/umd/popper.min.js"&gt;&lt;/script&gt;
    &lt;script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"&gt;&lt;/script&gt;

&lt;script&gt;
        // Initialize tooltips
        $(document).ready(function(){
            $('[data-toggle="tooltip"]').tooltip();
        });
    &lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>
</div>
</div>
</div>
</div>
<ul>
<li><strong>Explanation</strong>:
<ul>
<li><code>data-toggle="tooltip"</code>: Activates the tooltip feature.</li>
<li><code>data-placement="top"</code>: Controls tooltip position (<code>top</code>, <code>bottom</code>, <code>left</code>, or <code>right</code>).</li>
<li><code>title</code>: Sets the text displayed in the tooltip.</li>
</ul>
</li>
</ul>
<h3>2. Tooltip Positioning</h3>
<p>To control where the tooltip appears in relation to the element, use the <code>data-placement</code> attribute with options:</p>
<ul>
<li><code>top</code>, <code>bottom</code>, <code>left</code>, or <code>right</code></li>
</ul>
<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;button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on the right"&gt;
    Tooltip Right
&lt;/button&gt;
</code></pre>
</div>
</div>
</div>
</div>
<h3>3. Tooltip Options</h3>
<p>Tooltips have various customization options, such as delay and trigger.</p>
<p><strong>Example with Delay</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;button type="button" class="btn btn-info" data-toggle="tooltip" data-placement="bottom" title="Delayed tooltip" data-delay='{"show":"500", "hide":"100"}'&gt;
    Delayed Tooltip
&lt;/button&gt;
</code></pre>
</div>
</div>
</div>
</div>
<p><strong>Explanation</strong>:</p>
<ul>
<li><code>data-delay='{"show":500, "hide":100}'</code>: Adds a 500ms delay before showing and 100ms delay before hiding.</li>
</ul>

<h3>4. Programmatically Show or Hide Tooltip</h3>
<p>You can use JavaScript to control tooltips manually.</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">javascript</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>$('#myTooltip').tooltip('show');  // Show the tooltip
$('#myTooltip').tooltip('hide');  // Hide the tooltip
</code></pre>
</div>
</div>
</div>
