I have a large document with large cells (12 cells per page). I'm trying to
make flashcards. I want to type different amounts of text in each cell with
different font sizes and styles. I'm finding that the grid lines sometimes
move as I type, changing the size of the cells.

I want the cells to stay fixed size. How can I do that?

Thanks :-)
