Hm, okay I did not know where elswehere to put it.

<?php

/**
 * Archive Topic Content Part
 *
 * @package bbPress
 * @subpackage Theme
 */

?>

<div id="bbpress-forums">

	<?php if ( bbp_allow_search() ) : ?>

		<div class="bbp-search-form">

			<?php bbp_get_template_part( 'form', 'search' ); ?>

		</div>

	<?php endif; ?>

	<?php bbp_breadcrumb(); ?>

	<?php if ( bbp_is_topic_tag() ) bbp_topic_tag_description(); ?>

	<?php do_action( 'bbp_template_before_topics_index' ); ?>

	<?php if ( bbp_has_topics() ) : ?>

		<?php bbp_get_template_part( 'pagination', 'topics'    ); ?>

		<?php bbp_get_template_part( 'loop',       'topics'    ); ?>

		<?php bbp_get_template_part( 'pagination', 'topics'    ); ?>

	<?php else : ?>

		<?php bbp_get_template_part( 'feedback',   'no-topics' ); ?>

	<?php endif; ?>

	<?php do_action( 'bbp_template_after_topics_index' ); ?>

</div>

So this obviously does not go into css, so do you know where inside my child theme should I put the content-archive-topic.php code?
