* @package WordPress
* @subpackage Project_Zero
* @since 0.1

* This is a catch-all template for any pages that do not have a specialised template.
* You can find out more about the Template Hierarchy at

* Typically, index.php contains your blog archive template (content that could also be displayed in a home.php file).
* However, it is used for any content that does not have a specific template.

// Main Stylesheet
wp_enqueue_style('main', get_stylesheet_directory_uri().'/css/main.css');A stylesheet named css/admin.css is available to add styles to your admin area. It is called in functions.php, on line 26.
wp_enqueue_style('admin_styles', get_stylesheet_directory_uri() . '/css/admin.css');As well as the theme specific files, there are some template parts or includes that have been saved.
