|
|
*
|
|
* When using a child theme (see https://codex.wordpress.org/Theme_Development and
|
|
* https://codex.wordpress.org/Child_Themes), you can override certain functions

* 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.
|
|
*
|
|
* Functions that are not pluggable (not wrapped in function_exists()) are instead attached
|
|
* to a filter or action hook.
