To ensure a presentation has a cohesive look, what should be applied?

To ensure a presentation has a cohesive look, it is crucial to apply a consistent theme from the "Design" tab. A consistent theme helps unify the overall appearance of the slides, including background colors, font styles, and layout. This uniformity allows the audience to focus on the content without being distracted by varying styles or visual elements that could detract from the presentation's message.

Distinctive designs for each slide may lead to a fragmented look, making it difficult for viewers to follow the flow of information. Similarly, individual animations can be engaging, but when overused or improperly matched with the slide content, they can create visual chaos that undermines the presenter's professionalism and makes the material harder to digest. Using varied fonts for emphasis may add interest, but if not carefully managed, it can result in a disorganized and inconsistent presentation. Therefore, applying a consistent theme from the "Design" tab is the best approach to achieve a polished and cohesive look throughout the presentation.
