Custom page-.php

Hello, your theme looks great. However I was wondering about how to add custom pages.

Your default page (page.php) is this,

get_header(); ?>

	<?php fruitful_get_content_with_custom_sidebar('page'); ?>

<?php get_footer(); ?>

I have page with a slug, so I would create page-<slug>.php

Should I place my content between header and footer? I’ve tried it but neither header or css styles are loaded.
