Set a deck theme
Open Theme in the editor’s task pane. Choose a theme family, then adjust its colors and heading and body fonts. Use the slide preview to check text and chart contrast.
Set Slide size to 16:9, 16:10, or 4:3. That ratio applies throughout the deck. Editor, presenter, audience display, and participant Slide view preserve the same slide composition; unused screen space is letterboxed as necessary.
Changing the ratio changes the available canvas shape. Review every slide for overflow after changing it.
Create and apply a master
A master supplies recurring decoration, margins, backgrounds, logo, and footer.
- Under Slide masters, select an existing master or choose New master.
- Enter a Master name.
- Set Content margin, decoration, footer, and background.
- Add a logo and a useful Logo description if needed.
- Choose Use on this slide for the selected slide or Set as default for the deck’s default master.
The content margin ranges from 3% to 12%. A deck supports up to 20 masters. Remove master · use deck default removes a selected master and returns its uses to the deck default; at least one master remains.
Configure backgrounds and logos
Choose Solid or Gradient for a color background. For a gradient, set both colors and the angle. Use Choose background image to select a file or Use an image address to provide an address. Adjust focal points to keep the important part visible; set the overlay color and opacity to maintain readable text.
Use Choose logo image for a logo, then enter its description. Remove logo clears it. Use theme background restores the master’s theme background.
Uploads require an editable space. Desktop can embed chosen image files into a local .openroom file. See media formats and storage.
Override one slide
Under This slide, choose Customize this background to override the master’s background. Use master background removes that override. Select Hide logo, footer and decoration when a slide needs an uncluttered canvas.
Reset to deck master clears the slide’s design overrides while retaining its template association. Review the result before continuing.
Create a shared brand kit
Required: editor or owner access for authoring, plus branding availability on the space owner’s account.
- Open Space settings → Brand kits.
- Select New brand kit.
- Enter a Kit name and configure its colors, typography, masters, backgrounds, and logo.
- Review the chart palette preview and any contrast warnings.
- Select Save brand kit.
Open an existing kit and select Edit brand kit to revise it. Its detail page provides Move to trash; the brand-kit Trash provides Restore brand kit according to your management permissions.
Apply a brand kit
In the deck editor’s Theme pane, choose a kit under Brand kit and select Apply to all slides.
Applying copies the kit’s colors, fonts, and masters into the deck and resets individual slide backgrounds to the kit. Slide content and layouts remain in place. The copied design belongs to the deck, so a later change to the shared kit requires another explicit application to that deck.
Change the live interface theme
Live session controls also provide the shared interface themes Default, Chalkboard, Paper, Projector, and Sherbet, with light/dark presentation where available. These control session interface styling. The deck’s saved design remains the source of its slide composition.
