我可以在此Wordpress查询中为div添加ID吗？

Question

I'm using this PHP snippet to wrap every 12 Wordpress posts in a div.

<?php
    $i = 1;
    echo '<div class="row content-block">';
    if ( $project->have_posts() ) :
    while ( $project->have_posts() ) : $project->the_post();
        get_template_part('project', 'content');
    if($i % 12 == 0) {echo '</div><div class="row content-block">';}
    $i++; endwhile; endif;
    echo '</div>';
?>

Is there any way that I can apply unique ID's to the row content-block divs? for example block-1, block-2, etc/

Yes (edited):

<?php
    $i = 1;
    $id = 2;
    echo '<div class="row content-block" id="block-1">';
    if ( $project->have_posts() ) :
    while ( $project->have_posts() ) : $project->the_post();
        get_template_part('project', 'content');
    if($i % 12 == 0) {echo '</div><div class="row content-block" id="block-' .$id .'">'; $id++;}
    $i++; endwhile; endif;
    echo '</div>';
?>
