我想在中为第二页应用不同的样式single.php 或帖子。我该怎么做？

我有以下代码single.php 将页面拆分为两部分：

<!--nextpage-->

如果有其他方法可以添加另一个“选项卡”到帖子或类似内容，我非常感谢您的帮助……我只想在帖子中添加一个“自定义页面”，就像帖子的图库一样，因此URL可以如下所示：

http://localhost/mysite/1024/postname/gallery/
http://localhost/mysite/1024/postname/custom-page/

代码输入single.php:

    <?php get_header();?>
 <main>
<?php get_sidebar() ?>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

    <div id="post">

            <div class="top-single-movie">

            <div class="info">  
            <h3 class="title" id="post-<?php the_ID(); ?>">
            <a href="<?php the_permalink() ?>" rel="bookmark">
            <?php the_title(); ?></a>
            <?php if( get_field(\'date\') ): ?>
             ( <?php the_field(\'date\'); ?> )
            <?php endif; ?> 
            </h3>
            </div>


            <?php if(has_post_thumbnail()) :
            the_post_thumbnail(\'medium\');
            else : 
            echo \'<img src="\'.get_bloginfo(\'template_directory\').\'/img/default.png">\';
            endif;
            ?>

            </div><!-- End. top-single-movie -->


            <?php the_content(); ?>

            <?php

    ) );

            </div><!-- End. content-single-movie -->


            <p class="tags"><?php the_tags(); ?> </p> 



            <!--?php comments_template(); // Get comments.php template ?-->

            <?php endif; ?>
            <!-- END Loop -->


            <ul class="navigationarrows"> 
            <li class="previous">
            <?php previous_post_link(\'&laquo; %link\'); ?>
            <?php if(!get_adjacent_post(false, \'\', true)) 
            { echo \'<span>&laquo;Previous</span>\'; } ?>
