How to add ‘inner’ body class to all inner pages in WordPress

WordPress automatically adds ‘home’ class to ‘body’ element for the site’s homepage/front page. Wouldn’t it be handier to have a ‘inner’ body class for all the other pages?

This can be done by adding the following in child theme’s functions.php:

	add_filter( 'body_class', 'sk_body_class' );
	/**
	* Add "inner" class to 'body' element for inner pages
	* i.e., for all pages other than site's homepage/front page.
	*

	*/
	function sk_body_class( $classes ) {
	if ( ! is_front_page() ) {
	$classes[] = 'inner';
	}
	return $classes;
	}
