Part 4/7:
Slide Size enables you to change the dimensions of your presentation. You can opt for standard or widescreen formats and even create custom sizes suited to your display needs, such as portrait orientation for monitors or TVs set up vertically.
The Format Background feature further assists in personalizing your slides. You can select from various backgrounds, including solid fills, gradients, and textures. Each option allows you to explore distinct visual styles—from bold colors to subtle gradients—which can enhance the appeal of your slides significantly.
