I want to make a child theme for twentyfifteen theme in WordPress to show in right-to-left direction. I read the documentation on that in Codex. But to be honest, the documentation was good for a general outline of the setup but not so clear on details and in case the theme already has an RTL support.

These were my steps:

created a child theme directory named twentyfifteen-ar

created a file functions.php inside the directory that only contains:

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );


created style.css file inside the same dir that only contains:

Theme Name: Twenty Fifteen AR
Theme URI: https://wordpress.org/themes/twentyfifteen/
Author: me
Version: 1.0
Template: twentyfifteen

After that, activated the newly appearing theme Twenty Fifteen AR but nothing changed from the parent theme. What am I missing please?

Follow Up Question:

I want to add this to CSS of rtl.css file for example (where to put this code?)

            background-color: #f7f7f7;
            border: 2px solid #0f0;


  1. when created rtl.css inside child theme folder and added this code, website didn't pick up the change.
  2. Worked only when I added this code in the parent rtl.css file of the parent 2015 theme, but I know this is not the best practice as it will soon be replaced of the new version of the theme when is out there. So how should I add this code in this case?

You also need to include the RTL.css file which is in the theme too:

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
 wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
  wp_enqueue_style( 'rtl-style', get_template_directory_uri() . '/rtl.css' );

To use the rtl.css from your theme directory change the code to:

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
 wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
 wp_enqueue_style( 'rtl-style', get_stylesheet_directory_uri() . '/rtl.css' );

Make sure you copy everything from the original rtl.css file to your own.

  • the parent theme twentyfifteen does have rtl.css file, do I need to create another rtl.css file inside the child theme directory? if yes, what should its content be? – doctorate Jun 8 '16 at 17:31
  • no, look at my code, I am puiling it in so it should then make the theme RTL – Gareth Gillman Jun 8 '16 at 17:32
  • I see, great, I tried your kindly provided code and it worked, now I have RTL 2015 theme. Thanks. – doctorate Jun 8 '16 at 17:34
  • wish I had enough points to add the tag right-to-left. – doctorate Jun 8 '16 at 17:35
