Add a slide background
The briefing slide background is set to the background color from the current theme, but you can override this and apply the following styles:
Solid color
Gradient
Image
Use the following steps to add a slide background:
Click the Slide actions button
on the top edge of the slide.Click Change background.
Choose a Background style option.
For Color, choose a color by clicking a swatch or setting a custom color.
For Gradient, choose a gradient option.
For Image, click Add image and upload a background image.
Note:
Only one background style can be applied at a time.
A background set on a slide will persist if the theme is changed.
You may have to adjust text colors on the slide if you choose a color or gradient that is very different than the original theme background color.
When using an image, use a 16:9 image with background elements that do not conflict with areas where you plan to add text.
