Page design is a critical aspect of children's books that combines creativity with functionality. It involves the thoughtful arrangement of illustrations, text, and white space to create pages that are engaging and easy to read. Good page design helps to capture a child's attention and enhance the storytelling experience, ensuring that images and words complement each other. It considers factors such as font choice, color palettes, and the rhythm of page turns, ultimately aiming to foster a love of reading in young audiences.
