<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>
