Use Background Color
If enabled, the specified color will be used as the background when no presentations are displayed. If presentations are displayed, their background colors will take precedence.
Color
Click the drop-down button to choose a background color. You can select:
A solid color
A gradient with two or three colors
A texture or pattern
(See “Using the Color Picker” for a full description of options.)
No Background Color
Selecting this option makes the background completely transparent for both the presentation element and any displayed presentations.
When “No Background Color” is selected, the background of the page where the presentation element is placed will always be visible, even when presentations are playing.
If a presentation has its own background color, enabling No Background Color will override it.
For a partially transparent effect, set the Color property to a semi-transparent value. This allows the background to remain visible when no presentation is playing, while still showing the background colors of the presentations when they are displayed.
