| <h2>About JavaScript tabs</h2> | |
| <div> | |
| <p>JavaScript tabs partition your Web page content into tabbed sections. Only one section at a time is visible.</p> | |
| <p>The code is written in such a way that the page degrades gracefully in browsers that don't support JavaScript or CSS.</p> | |
| </div> | |
| </div> | |
| <div class="tabContent" id="advantages"> | |
| <h2>Advantages of tabs</h2> | |
| <div> | |
| <p>JavaScript tabs are great if your Web page contains a large amount of content.</p> | |
| <p>They're also good for things like multi-step Web forms.</p> | |
| </div> | |
| </div> | |
| <div class="tabContent" id="usage"> | |
| <h2>Using tabs</h2> | |
| <div> | |
| <p>Click a tab to view the tab's content. Using tabs couldn't be easier!</p> | |
