Keynote makes it easy to create beautiful presentations. Start with one of the themes. Each theme comes with predesigned styles—coordinated sets of colors, borders, effects, and so on—for text, shapes, photos, video, and other objects.
When you select an object, tap
to see the formatting controls. Only controls for the type of object you select are shown.

Tap one of the alternative style designs to change the object’s look. Use the style options to customize the object’s appearance however you like.
