How to add a class to post-meta?

[meredi]

My purchased child theme is set up in such a way that blog entry styles are used both on the entry pages and for entry promos on the homepage.

I would like to style these differently — for instance, I'd like there to be a different separator for the "post-meta" section when it's shown on an entry on the homepage, than when it's shown on the entry page itself.

I was hoping to do this by adding a different class to "post-meta" depending on whether I'm on an entry page or not.

This is kind of where I'm at:

add_filter( 'genesis_post_meta', 'darling_post_meta_filter' );
function darling_post_meta_filter( $post_meta ) {

	if ( is_singular( 'post' ) ) {
		$post_meta = '[post_categories before="Featured in: "] [post_comments zero="0" one="1" more="%"]';
		/* $post_meta['class'] .= 'my-custom-class'; */
	} else {
		$post_meta = '[post_categories before=""] [post_comments zero="0" one="1" more="%"]';
	}
    return $post_meta;

} 

The commented section where I'm trying to add the class is NOT working. Does anyone have any suggestions? There are no unique enclosing parent classes on the homepage so I don't believe I can do this just with CSS.

Sigh, a kind person on another forum pointed out that each page actually does have a unique class, which I can use to style things differently. I was looking for this but didn't look in the "body" tag so didn't discover the "home" class, for instance. That saves me from updating functions.php and makes this purely a CSS fix.

Sorry, I'd delete the post if I could but I can't!
