Mosaic Layout Guide

A Mosaic Layout Gallery is an image gallery where photos use different sizes and span across rows and columns. It helps show images in an eye-catching way and improves visual storytelling on WordPress websites.

Let’s see how to create a Mosaic Layout Gallery in WordPress.

Scrolling down the tab, come to the Caption Settings. There are two setting types – Caption Type and Caption Visibility.

Caption Type lets you set where the caption will be displayed. It has three options: Below Image, Full Overlay, and Bar Overlay.

Caption Visibility allows you to configure how the caption will be displayed. This could be Always Visible, Show on Hover, or Hide on Hover.

Conclusion #

Thus, you can create mosaic galleries on the WordPress block editor using the Galleryberg plugin. This layout keeps visitors engaged and makes your WordPress site look modern and professional.

But to get the best, keep a clear visual balance between large and small images. Do not overload the gallery with too many photos. Leave enough spacing.
