Código PHP:
<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">
<?php if ( $user_ID ) : ?>
<p>Logged in as <a href="<?php echo get_option('siteurl'); ?>/wp-admin/profile.php"><?php echo $user_identity; ?></a>. <a href="<?php echo get_option('siteurl'); ?>/wp-login.php?action=logout" title="<?php _e('Log out of this account') ?>">Logout »</a></p>
<?php else : ?>
<div class="postinput">
<p><input type="text" name="author" id="author" value="<?php echo $comment_author; ?>" size="22" tabindex="1" />
<label for="author"><small>Name <?php if ($req) _e('(required)'); ?></small></label></p>
<p><input type="text" name="email" id="email" value="<?php echo $comment_author_email; ?>" size="22" tabindex="2" />
<label for="email"><small>Mail (will not be published) <?php if ($req) _e('(required)'); ?></small></label></p>
<p><input type="text" name="url" id="url" value="<?php echo $comment_author_url; ?>" size="22" tabindex="3" />
<label for="url"><small>Website</small></label></p>
<?php endif; ?>
<p><small><strong>XHTML:</strong> You can use these tags: <?php echo allowed_tags(); ?></small></p>
<p><textarea name="comment" id="comment" cols="100%" rows="10" tabindex="4"></textarea></p>
<p><?php do_action('comment_form', $post->ID); ?></p>
<p><input name="submit" type="submit" id="submit" tabindex="5" value="Submit Comment" title="Please review your comment before submitting" />
<input type="hidden" name="comment_post_ID" value="<?php echo $id; ?>" />
</p>
</div>
</form>
Alguna idea que me oriente sobre donde mirar en el CSS?. Por cierto mi style.css lo podeis ver AQUI
Un saludo, y gracias por su tiempo
