10.1 The slide master and a real theme
Every slide is consistent because the master makes it so.
Before:09. PowerPoint — CoreUnlocks:13. Portfolio & Certification
The slide master is where a deck's consistency actually lives: layouts, placeholders, theme colours and fonts, defined once and inherited by every slide. This topic covers building a branded template others can use and rebuilding an inherited mess on a proper master. It opens the design module because the master is the mechanism the design principles get applied through. The common confusion is fixing slides one by one — realigning the same stray title on forty slides — when the master would fix all of them at once.
Work through these
Slide master, layouts and placeholders
The master holds the elements that repeat, the layouts define slide types, and placeholders are the boxes content goes into. Editing the master once beats editing forty slides.
Theme colours, fonts and effects
A theme sets colours, fonts and effects across the whole deck, so a change of palette is one action. It is also what keeps a deck looking like it came from one place.
Building a branded template others can use
A branded template built on a master is what lets colleagues produce consistent decks without design decisions. This is the deliverable rather than an exercise.
Fixing an inherited deck by rebuilding it on a master
An inherited deck full of hand-placed boxes is usually faster to rebuild on a proper master than to repair. Recognising that moment saves hours of nudging.
