The Box Model
In Chapter 5, you used padding to create some space between the content and border of the newsletter box and
changed the border properties. By making these changes, you affected the box model of the main newsletter ele-
ment <form id=”newsletter” action=”#”> .
Now add some margin and padding to the footer to better understand these properties:
1. In styles.css, below the other declarations in the #footer rule set, add the following:
margin-top: 2.5em;
padding: 1.4em 0;
2. Save styles.css.
Here, you change the box model of the <footer id=”footer” role=”contentinfo”> element, as shown
in Figure 7-1.
