Slide Layouts
A slide layout inherits slide properties from the corresponding slide master and sets layout information for all presentation slides that utilize this layout. Each presentation slide has the ability to override any of this information that it chooses by specifying local attribute values within the presentation slide. Much like the slide master, the slide layout contains some common structural elements:
Common Slide Data - Common properties and layout information that will override properties set within the slide master but will be inherited by all presentation slides that utilize this layout.
Color Map Override - Color Mapping that will override the inherited color mapping from the slide master but will be inherited by all presentation slides that utilize this layout.
Header and Footer - Header and footer properties that will override properties set within the slide master but will be inherited by all presentation slides that utilize this layout.
Timing Information - Common timing properties used for animation, controls, etc. These will override properties set within the slide master but will be inherited by all presentation slides that utilize this layout.
Transition Information - Slide transitioning information to be inherited by each presentation slide. These will override properties set within the master slide but will be inherited by all presentation slides that utilize this layout
The above list defines the areas that can be used to override inherited components from the master slide. That is, these can be specifically defined on a per-layout basis via the above elements.
