When you insert a frame into a page, the text on the page moves aside to create space for the frame - in other words it flows around the frame. This is the default behavior for frames. There are two other options, which you can set as follows:
Click in a frame to make it active.
Right-click and select the Frames command from the shortcut menu (or select the Frames and Callouts command from the Format menu).
In the Text Wrapping group box, choose from:
None - flow of the body text stops at the top of the frame and continues at the bottom.
Around - the default setting. Body text wraps around the frame.
Transparent - body text flows under the frame and the frame itself is transparent.
