/**
 * Astra functions and definitions.
 * Text Domain: astra
 * When using a child theme (see https://codex.wordpress.org/Theme_Development
 * and https://codex.wordpress.org/Child_Themes), you can override certain
 * functions (those wrapped in a function_exists() call) by defining them first
 * in your child theme's functions.php file. The child theme's functions.php
 * file is included before the parent theme's file, so the child theme
 * functions would be used.
 *
 * For more information on hooks, actions, and filters,
 * see https://codex.wordpress.org/Plugin_API
 *
 * Astra is a very powerful theme and virtually anything can be customized
 * via a child theme.
 *
 * @package     Astra
 * @link        https://wpastra.com/
 * @since       Astra 1.0.0
