Hello, first, create the template in the following format page_custom.php
<?php
/*
Template Name: Custom_Page_Timtable
*/
?>
<?php get_header(); ?>
<div id=”content” class=”narrowcolumn”>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class=”post” id=”post-<?php the_ID(); ?>”>
<div id=”wrapper”>
<div class=”efectoimg”>
<span></span><div class=”post-it”> TIMETABLE </div>
<div class=”fondo”>
<?php the_content(‘<p class=”serif”>Read the rest of this page ?</p>’); ?>
<?php wp_link_pages(array(‘before’ => ‘<p>Pages: ‘, ‘after’ => ‘</p>’, ‘next_or_number’ => ‘number’)); ?>
</div>
</div>
<?php endwhile; endif; ?>
<?php //edit_post_link(‘edit’, ‘<p>’, ‘</p>’); ?>
</div>
</div>
<?php get_footer();
?>
Second: edit page in wordpress and adding template
