<h4>How to Use WP Colorbox</h4>
Pop up image in lightbox
Create a new post/page and use the following shortcode to create a text/image link which will trigger lightbox once clicked:
<pre><code>[wp_colorbox_media url="https://example.com/wp-content/uploads/images/overlay.jpg" type="image" hyperlink="click here to pop up image"]
</code></pre>
here, url is the link to the media file that you wish to open in lightbox and hyperlink is the anchor text/image.
<pre><code>[wp_colorbox_media url="https://example.com/wp-content/uploads/images/overlay.jpg" type="image" hyperlink="http://example.com/wp-content/uploads/images/thumb.jpg"]
</code></pre>
Pop up YouTube video in lightbox
<pre><code>[wp_colorbox_media url="https://www.youtube.com/embed/nmp3Ra3Yj24" type="youtube" hyperlink="click here to pop up youtube video"]
</code></pre>
Pop up Vimeo video in lightbox
<pre><code>[wp_colorbox_media url="https://www.youtube.com/embed/1284237" type="vimeo" hyperlink="click here to pop up vimeo video"]
</code></pre>
Specify an Alternate Text for an Image
<pre><code>[wp_colorbox_media url="https://example.com/wp-content/uploads/images/overlay.jpg" title="overlay image" type="image" hyperlink="http://example.com/wp-content/uploads/images/thumb.jpg" alt="Thumbnail image description"]
</code></pre>
Apply Custom CSS
You can specify your own CSS class in the shortcode to customize a text/image link.
<pre><code>[wp_colorbox_media url="https://www.youtube.com/embed/nmp3Ra3Yj24" type="youtube" hyperlink="click here to pop up youtube video" class="custom_class"]
</code></pre>
Multiple CSS classes can be separated with a space. For example:
<pre><code>[wp_colorbox_media url="https://www.youtube.com/embed/nmp3Ra3Yj24" type="youtube" hyperlink="click here to pop up youtube video" class="custom_class custom_class2"]
</code></pre>

WP Colorbox

Having to go to a website to see how to use this should be a huge no-no. Will not recommend this plugin to anyone.

Missing in-plugin documentation

View image, video (YouTube, Vimeo), page, inline HTML, custom content in lightbox. Add jQuery Colorbox lightbox effect to your WordPress site.
