WP Colorbox is a simple, lightweight plugin that allows you to add lightbox effects to your WordPress site. With WP Colorbox, you can add lightbox to images, videos, inline HTML elements, or custom content.
The plugin allows you to use any image or text link to trigger a lightbox popup effect. You can also use a lightbox shortcode to include the effect on any page or post. In addition to all of the images above that you can apply the lightbox effect to, the plugin also allows you to apply the lightbox to an iFrame, meaning you could potentially open up forms or external web pages from your site using the lightbox feature. This plugin is a great and simple tool to use to quickly add a lightbox effect to some elements on your sites.
