Can you put white space outside a textbox?

[WISEMANOFNARNIA]

When I put pictures in my publisher file, sometimes I want captions
for the pictures. So I make a tiny textbox that I put under the
picture, and type in a caption into that textbox. The problem is that
I can make the picture have some space to left and right of it so that
text doesn't crowd into the picture, but I can't do that with the
textbox containing the caption. Is there any way to prevent outside
text from crowding the borders of a textbox?

You can move that textbox wherever you need. You don't need to leave space
inside when you can steer clear of the textbox itself.

You can change the text box margins. Right-click the text box, click format text
box, Text box tab.

Not sure this is what you are asking. You can change the image distance from
text. Select the picture, click format picture, Layout tab, un-check Automatic.
