karinnelegault on "Different class on certain categories - get_the_category_list"

Hi,

In the functions.php theres'

$categories_list = get_the_category_list( __( ', ', 'twentythirteen' ) );
	if ( $categories_list ) {
		echo '<span class="categories-links">' . $categories_list . '</span>';
	}

How to I apply a class to an <li> of a certain category?

Thank you!
