You can customize the “Image Gallery Items “using the Combo Blocks plugin. This article will help you to style the Image Gallery items.
To get started, add the “Image Gallery” block.
Next, select a variation. For instance, I chose the “Layout-2” variation.
Now select any one of the image gallery items. Then click on the wrapper tab.
Here you can modify the wrapper tag to H1, H2, H3, H4, H5, H6, SPAN, DIV, and P tags.
