When the Lightbox gallery has been opened, the captions for each image or video can be styled by the Lightbox Title and Description text frame. Much like the Thumbnail Title and Description text frame, use the text frame to adjust the color, font, size and text alignment of the Title and Description for your Lightbox. For spacing and padding customization, use the appropriate Text and Icon section found within the Container widget.
When using multiple galleries on one page or if you change the name of your gallery within the Container widget, please be sure to change the Tooltip name of the Text Frame within the Hyperlinks>Tooltip panel.
Container Name: AboutPhotos
Tooltip Name: Lightbox_AboutPhotos
