In Microsoft PowerPoint, slide design encompasses multiple elements, including:

• (a) Design template: A pre-designed layout that includes slide formats, placeholders, and background styles.
• (b) Color scheme: A coordinated set of colors applied to text, backgrounds, and objects on a slide to ensure visual consistency.
• (c) Animation scheme: Effects that add motion to text, images, or other slide elements, enhancing the visual appeal and dynamics of the presentation.
