I using the following:
<?php if ($single) { ?>
<div class=”menu top-menu”>
<span class=”prev”>
<img src=”https://whatsbruin.net/images/l_arrow_plain.gif” alt=”l_arrow_plain.gif” align=”middle” /> <?php previous_post(‘%’, ”, ‘yes’, ‘no’, 1, ”) ?></span>
<span class=”next”><?php next_post(‘%’, ”, ‘yes’, ‘no’, 1, ”) ?> <img src=”https://whatsbruin.net/images/r_arrow_plain.gif” alt=”r_arrow_plain.gif” align=”middle” /></span>
</div>
<?php } ?>
But I am trying to “hide” the right arrow when the Permalink is displaying the most recent post.
