The difference between PowerPoint templates and themes
A PowerPoint template is a pattern or blueprint of a slide or group of slides that you save as a .pptx file. Templates can contain layouts, theme colors, theme fonts, theme effects, background styles, and even content.
Themes give your presentations a designer-quality look, that includes one or more slide layouts with coordinating colors, a matching background, fonts, and effects. Themes can also be applied to tables, SmartArt graphics, shapes, or charts in your slides.
PowerPoint offers several built-in themes, and you have unlimited options for customizing them. Built-in themes can be applied from the Themes gallery on the Design tab.
