Use the Text drop-down found within the Lightbox Container section to direct the alignment and spacing of your image and video titles and descriptions. To disable either the title or description from being displayed in the Lightbox, use the checkboxes found at the top of the section.
Position
Align the title and description of each thumbnail to the left, center or right of the browser. Select one of the dropdown options to apply to all text captions within your gallery.
Spacing
Much like the Thumbnail spacing found within the Container widget, use the spacing areas to control the padding and margin of the item captions within your Lightbox.
The space between the title and description is the area below the title and above the description. Use this area to add vertical spacing between the title and description within the textbox.
