Step-by-step explanation:
In slides and other visual aids, it is not recommended to use fancy fonts and many colors to create a more sophisticated presentation. Instead, it is important to keep a consistent visual style, including font, colors, and backgrounds, to maintain a professional and cohesive look. Using large enough visuals that are clear and of high quality is crucial for the audience to see and understand the content. Additionally, considering accessibility by providing space and time for the audience to engage with the presentation, making it accessible to individuals with different abilities, can greatly enhance its effectiveness.
