Why do it: To apply a colored gradient effect (overlay) over the background image or video of the slide, enhancing content readability.
Procedure:
1. Access the Slider editing screen and select the Slide you want to modify.
2. Within the Slide options, scroll down until you find the section titled Overlay.
3. Locate the field labeled Gradient.
4. Click on the button or selection area associated with the Gradient field, which displays the text Seleziona gradiente.
5. The gradient selection tool will open. Use this tool to define the direction and colors of the desired gradient.
6. Once selected, the system will immediately apply the gradient to the slide preview.
7. If you also want to apply a solid color and/or adjust the overlay opacity, use the adjacent fields Colore and Opacità.
8. After completing your changes, make sure to save by clicking on the save button (usually Salva modifiche or Avanti in guided mode).
