Foreach Columns & Pagination

I am using the plugin “Categories Images” and using a foreach statement that I am trying to adapt for display of 11 items in three rows for a yearly magazine archive. The 11 items are custom category images (each issue’s image cover with name and description). Each page of 11 items represents one year in the archive. I want to paginate backward and forward to brows each page/year. The items would display as such:

ABCD
EFGH
IJK

Here is the foreach code on its own:

foreach (get_terms('magarchive') as $cat) : ?>
    <a href="<?php echo get_term_link($cat->slug, 'magarchive'); ?>"><?php echo $cat->name; ?></h4> - </a><br>
    <em><a href="<?php echo get_term_link($cat->slug, 'magarchive'); ?>"><?php echo $cat->description; ?></a></em></h4><br>
    <a href="<?php echo get_term_link($cat->slug, 'magarchive'); ?>"><img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /></a>
    <?php endforeach; ?>

I’ve tried applying tables, css, arrays, etc. But I can only get the items to display in a single vertical column. I am just not skilled enough at this point with stylizing the echo of foreach’s output. Any help would be greatly appreciated. Thank you…
