How to define a class to category AND subcategory

  • Sorry in advance for my bad english ??
    I am searching how to define a class to a parent category AND the childs categories.
    This is the code I’m using for the parent category :

    <h1 <?php
if (is_category('fruits')) {echo 'class="fruits"';}
if (is_category('vegetables')) {echo 'class="vegetables"';}
?>><?php echo single_cat_title(); ?>
</h1>

    This code works fine for the parent category, of course. But how to define it ALSO for the subcategories ?
    Thank you in advance !!

    YEAY ! Finally, it works !!

    I used the code mentioned here .

    <?php
if ( ! function_exists( 'post_is_in_descendant_category' ) ) {
	function post_is_in_descendant_category( $cats, $_post = null ) {
		foreach ( (array) $cats as $cat ) {
			// get_term_children() accepts integer ID only
			$descendants = get_term_children( (int) $cat, 'category' );
			if ( $descendants && in_category( $descendants, $_post ) )
				return true;
		}
		return false;
	}
}
?>
<h1 <?php if ( in_category( 'fruits' ) || post_is_in_descendant_category( ID ) ) {echo 'class="fruits"';}
	  if ( in_category( 'vegetables' ) || post_is_in_descendant_category( ID ) ) {echo 'class="vegetables"';}
	  	?>><?php the_category(' / '); ?></h1>

    Happy me ??
