Can I change the presentation theme independently for different sildes?
For example, the slide 1-3 use the blank theme and the others use the while theme
Question marked as
Keynote can only have one theme within a Keynote presentation. However, Keynote can use as many Slide Layouts as you want in a single presentation.
Therefor, the workaround I use is to create separate Keynote presentations for each required theme, using a specific Slide Layout.
Then drag the slides from the Navigator in each presentation in to the Navigator of a new blank Keynote.
