I know tab2 does not have any sub divs, but I thought when the following code executes:
it looks for any divs within the div with content class and hides those divs. When I view the code (a small sub section of his code):
<h1>My first page with style</h1>
<p>Welcome to this page!</p>
<p>It has no images, but it got style.And it has links, to bring you somewhere else</p>
<p>On this page links are part of a navigation element: a menu. The menu contains links to other parts (tabs) inside this document. The page-logic is realized with jQuery.</p>

tab2 is contained with the div with the content class. I must be misinterpreting what the code actually is targeting.
