<p>A spinnaker is a special type of sail that is flown in front of the main sails. It’s packed away when not in use, but when the wind is right, it can be unfurled to provide a powerful boost. This plugin is named Spinnaker because it allows you to keep your images and PDFs neatly tucked away, ready to be “unfurled” into a beautiful, accessible lightbox when your users need them.</p>
<p>Spinnaker is a lightweight, modern, and highly accessible plugin that turns any image or PDF link into a fully-featured dialog lightbox. It’s built with accessibility as a priority, ensuring a seamless experience for users with keyboards and screen readers.</p>

<li>Supports custom initial image positioning (e.g., center, top, bottom, left, right).</li>
<li>Displays image credits as a “placard,” with support for links.</li>
<li>Provides a “Download” button for the full-size image.</li>

<h3>Usage</h3>
<h3>Image Lightbox</h3>
<p>To make an image open in a lightbox, add the class <code>image-lightbox-trigger</code> to the <code><img></code> tag itself.</p>
<p><strong>For Gutenberg Block Editor:</strong><br />
Gutenberg wraps images in a <code><figure></code> element. Add the class <code>image-lightbox-trigger-container</code> to the figure wrapper: Select the image block, open the “Advanced” panel in the block settings, and add <code>image-lightbox-trigger-container</code> to the “Additional CSS class(es)” field. For screen reader descriptions, you can use the image’s “Title” field (available in the image block settings). For advanced features like credits and positioning, switch to HTML editing mode.</p>
<p><strong>For Page Builders (like DIVI):</strong><br />
If you can only add a class to the container/module holding the image, add the class <code>image-lightbox-trigger-container</code> to the container. The plugin will find the first image inside it and turn it into a lightbox.</p>
<p><strong>Optional Attributes (add to the <code><img></code> tag):</strong></p>
<ul>
<li><code>data-description="…"</code>: A longer description for screen readers. <em>Note: Users of Gutenberg and other page builders that don’t allow custom attributes to be added can use the image’s “Title” field. The plugin will automatically use the title text for the screen reader description and remove the title attribute from the image to prevent duplicate announcements.</em></li>
<li><code>data-credit="…"</code>: The text for the credit placard. <em>Requires HTML editing mode in Gutenberg.</em></li>
<li><code>data-credit-link="…"</code>: A URL to make the entire credit placard a link. <em>Requires HTML editing mode in Gutenberg.</em></li>
<li><code>data-position="…"</code>: Set the initial scroll position. Options: <code>top</code>, <code>bottom</code>, <code>left</code>, <code>right</code>, or <code>center</code> (default). <em>Requires HTML editing mode in Gutenberg.</em></li>
</ul>
<p><strong>Localization:</strong><br />
To translate the UI text, add a language-specific class like <code>-es</code> (for Spanish) to the trigger class (e.g., <code>image-lightbox-trigger-es</code>).</p>
<ul>
<li><strong>Supported languages:</strong> Spanish (<code>-es</code>), Russian (<code>-ru</code>), Vietnamese (<code>-vi</code>), Simplified Chinese (<code>-zh</code>), Arabic (<code>-ar</code>), Korean (<code>-ko</code>), and Somali (<code>-so</code>).</li>
</ul>
<p><strong>Example HTML:</strong></p>
<pre><code><img class="image-lightbox-trigger-es" src="…" alt="…" 
     data-description="Una descripción detallada de la imagen." 
     data-credit="Foto por Jane Doe" 
     data-credit-link="[https://example.com](https://example.com)"
     data-position="right">
</code></pre>
<h3>PDF Lightbox</h3>
<p>To make a link to a PDF open in a lightbox, add the class <code>pdf-lightbox-trigger</code> to the <code><a></code> tag itself.</p>
<p><strong>For Page Builders (like DIVI):</strong><br />
If you can only add a class to the container/module holding the link, add the class <code>pdf-lightbox-trigger-container</code> to the container. The plugin will find the correct PDF link inside it.</p>
<p><strong>Localization:</strong><br />
To translate the UI text, add a language-specific class like <code>-es</code> (for Spanish) to the trigger class (e.g., <code>pdf-lightbox-trigger-es</code>).</p>
<ul>
<li><strong>Supported languages:</strong> Spanish (<code>-es</code>), Russian (<code>-ru</code>), Vietnamese (<code>-vi</code>), Simplified Chinese (<code>-zh</code>), Arabic (<code>-ar</code>), Korean (<code>-ko</code>), and Somali (<code>-so</code>).</li>
</ul>
<p><strong>Example HTML:</strong></p>
<pre><code><a href="/path/to/file.pdf" class="pdf-lightbox-trigger-es">Directorio</a>
</code></pre>
