Loved it as a developer as it has nothing but a plain fancybox.

Seamlessly integrates the fancyBox 3 script into your WordPress installation: Upload, activate, and you’re done. Additional configuration is optional.
You can easily customize almost anything you can think about fancyBox lightbox. By default, the plugin will use jQuery to apply fancyBox to ANY thumbnails that link directly to an image. It will also automatically convert WordPress image galleries into fancyBox galleries.
For Inline content linking 
– Create a link to any hidden or visible div with an ID attribate, and the plugin will transform the link and enable it for fancyBox usage. 
– Note: this may cause a conflict if your page or website is using a smooth scrolling function to jump between page sections!
In upcoming versions, additional functionality for ajax calls and iframe data will be implemented.
