I am confident this can be a simple one, but I am not getting luck foreseeing it right now.

I've multiple records that display fundamental information on the home page of my website, and that i would like them to click to see 'more info' for every.

How do you get this to work? I've got a single.php page setup, although not sure what's going to get this to like magic work.

here's the code for that home page:

<?php 
$loop = new WP_Query(array('post_type' => 'portfolio', 'posts_per_page' => 12)); 
?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php   
    $custom = get_post_custom($post->ID);
    $screenshot_url = $custom["screenshot_url"][0];
    $website_url = $custom["website_url"][0];
?>
    <div class="item">
    <a href="<?=$website_url?>"><?php the_post_thumbnail(); ?> </a>
    <h3><?php the_title(); ?></h3>
    <p><?php the_content(); ?></p>
</div>
    <?php endwhile; ?>
