* 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.
