Removing the margins from our paragraphs has brought the footer right up to the bottom
of our longest column (experiment with different amounts of content in each column—the result

#footer rule doesn't change anything, so instead we'll add margin-bottom:.5em to the wrapper
div surrounding columns one and two, and to column three ( .third-col ), which puts some
distance between the columns and the footer (Figure 14-16).
