I'm using the Simple Section Navigation widget to display Parent Page (section) specific menus. ie. When viewing a top level page that has children or one of the children - the page menu widget only displays links to that parent and the children/siblings. This works great.
What I now need to do, is change the style of other page elements based on the same logic. ie. When viewing a particular parent page or any of its child pages -> the side menu only shows this parent and sub-pages (currently working) AND a widget's background color changes... (or any given DIV has its style changed)
My only real attempt at this so far was to add this "test code" into style.php
Of course "is_page(77) won't give the parent/child relationship I'm looking for. It was more of an attempt at a "proof of concept". Unfortunately it proofed to be a poor concept

Code:
/* CUSTOM WIDGET COLORS */ <?php if is_page(77) { ?> $title = 'div.text-3 {background: #008400;}'; echo $title; <?php } ?>
So, any ideas would be greatly appreciated. even from novices like myself

Juggledad, if you're able to help I can offer more meager incremental payments

Thanks,
Jaxon
