Contrast is an important component of ensuring that the relationship beween your ideas is clear. If elements are not the same, use font, color, size, thickness, shape, and space to make them very different. Try consulting our PowerPoint template for basic format, and branching out from there to format your work in the most logical way.
Ask yourself: Can you see a clear difference between your headings and the other content material?
Alignment can help demonstrate the relationship between ideas, as well. All items on a slide should be aligned to demonstrate a clear structure or hierarchy and not simply placed on the slide arbitrarily. Proper alignment will highlight a clean design and clear organization.
Ask yourself: Does your alignment allow your audience to clearly follow and understand the hierarchy of your ideas?
