I have seen all the instructions for removing a side bar by creating a page-nosidebar.php, however all recommend editing the code
<?php get_sidebar(); ?> out of the page.php file and renaming it.
The trouble is that code doesn't appear in the page.php file in Billion.
Does anyone know how to create a template without a side bar for Billion, please?
I just want to make the one page (for displaying a full page Timeline JS) not change the whole theme.
