These boxes act as specified areas where you can add text or objects.One of the most common questions is How do I restart or reformat my page numbers partway through the document?I found 3 reasons that page numbers might not appear.

Here are some possible solutions for this situation: Note: The image could be on the slide master!In that situation, open the Slide Master, select the image and use one of the above techniques.

By using the master slides, you can add consistency to a presentation, making it easier to follow and understand.
Masters let you format the title, background, color, date, time, and slide number. The controls formatting only for the title slide(s).
The slide number is there, but the background is light and its slide master uses white text for the slide number.
In this case, the slide’s master has a dark background, but I had changed the background for the individual slide.
