Spry Tabbed Panels - 2 lines of tabs

Question

I have a "Spry Tabbed Panels" widget on one of my site's
pages and it works great. Except there are now more tabs than will
fit side-by-side, so the last one gets moved to a new line, below
the first 4. That's not that big a deal, except there's now a large
blank space underneath and to the right of the top-row tabs.
Is there any way to edit the CSS or page's codes (like adding
an extra DIV surrounding the widget) so the now empty space gets a
background color matching inactive tabs?
To replicate this: create a fixed-width tabbed panels widget
and simply add more tabs than there will fit in the widget's width.
Any help on this matter would be appreciated.
Edit: I've made a slight change to the CSS file so the tabs
now have a fixed width, filling up 1/3rd of the widget's width
each. I'd like to have the empty space look better, but this'll do
for now.

Answer 1

First add an ID to the tab as follows or similar
<h2 id="second">Tab 2</h2>
Then add a style rule to add a background image as follows or similar
.TabbedPanelsTab#second {
    background:url(myImage.gif);
