With this theme, you can easily create galleries like the one you see below. No third-party plugins or shortcodes needed. Just use the obvious ‘Essentialist Gallery’ Gutenberg block (or WP’s native gallery if you’re not into Gutenberg).
Your photos’ previews are formed into collages automatically. Look at how neatly these 6 images have stacked:
The galleries have a fullscreen mode (lightbox) with zoom and individual picture sharing functionality (Facebook, Twitter, Pinterest). Individual picture sharing can be switched on/off in your Admin Panel. On mobile, you can exit the lightbox view by simply swiping up or down — that’s what we’ve all got used to with the Facebook’s mobile app.
