EC Lightbox

EC Lightbox is a minimal WordPress plugin that adds a modern lightbox to galleries using GLightbox.

The plugin is opt-in by behavior: once activated, it only applies its lightbox functionality to blocks where you explicitly add a custom CSS class (for example, a Gallery block). Everywhere else, WordPress behaves normally.

Features

• Uses GLightbox for a clean, responsive lightbox.
• Works with WordPress core blocks (e.g. Gallery, Image).
• Opt-in activation via a custom CSS class (ec-lightbox).
• Groups images by gallery container (each block with ec-lightbox is its own gallery).
• Includes a Settings page in WordPress Admin.

• PHP 7.0+
• A block-base…
