<p>Creating tabs is a fairly trivial and common practice in web design, but many times it requires JavaScript to properly implement. Fortunately it <em>is</em> possible to create tabbed content with only using CSS.</p>

-<p>While this method is semantic and accessible, you might consider using a pre-existing plugin for tabbed data.</p>
-<p>This component tends to feel a little "stiff" compared to more fleshed out variations available. This pure CSS version is better suited as a fallback for when users have disabled JavaScript.</p>
