Overview
One of the benefits of separating content from presentation is flexibility. By using CSS to control a site's layout (as we saw in Chapter 12), we can control an entire site's design. Change a few rules, and instantly and dramatically update thousands of pages.
Just one example of the flexibility gained from choosing to use CSS to control a site's layout comes from styling the <body> element. By adding a class or id to the <body> tag, you can take advantage of customized control over any element on the page, eliminating the need for duplicating shared rules.
In this chapter, we'll discover how adding class to the <body> element enables us to toggle between two separate layouts while sticking with the same markup structure.
