Spry Tabbed Panels 2.0 have a number of support files to make them run.
<!--files for Spry Tabbed panels-->
<link type='text/css' href='../Spry-UI-1.7/css/TabbedPanels2/SpryTabbedPanels2.css' rel='stylesheet'/>
Below, I have a Spry demo page with 3 widgets on it. If you look at the source code, you'll see how the the various support files are organized.
Function code is near the bottom of the page.
Second question: How can I add text to each page/ tabbed panel, like here http://ppbm6.com/Planning.html
Turn off CSS. View > Style Rendering > un-tick Display Styles. You'll see an unstyled HTML page in Design View. But this won't effect styles in Live View or Preview.
