Step 1: Open the presentation you are editing.

Step 2: Click the Style drop-down menu on the top bar.

3. Select New Style

Note: When changing styles this will not change any images that can be changed via the editor. It can only modify the position and styling of items. For example, main menu images will remain the same between styles, this will need to change manually.

See Edit Branding for information on finer customizations that can be made.
