How do you change the visual editor’s background color?

The question:

I have a WordPress site in which the background color is black and the text is white. The site is fine, but it’s a pain trying to edit content in the visual editor as the background is white (same color as the text). I end up having to tell users to use the HTML view or write up the content in black color text and then at the end just select all the text and flip it to white (in which case many of them freak out and think their text is now deleted!)

How do I change the background color of the editor to black (or any other color) so that the content can be readable if the text color is to be white?

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

similar to the answer by GavinR, using the wordpress add_editor_style() function; (as implemented in Twenty Ten and Twenty Eleven)

in functions.php of your theme, add:


then create an editor-style.css in your theme folder:

.mceContentBody.wp-editor {     
  background-color: #000;
  color: #fff; 

Method 2

First, add a CSS file in your theme directory (I’m calling it tiny.css). Then add the following to your theme’s functions.php:

// Add custom styles to TinyMCE editor
if ( ! function_exists('tdav_css') ) {
    function tdav_css($wp) {
        $wp .= ',' . get_bloginfo('stylesheet_directory') . '/tiny.css';
        return $wp;
add_filter( 'mce_css', 'tdav_css' );

Finally, add this CSS to tiny.css

.mceContentBody.wp-editor {

… replacing #000000 with the HTML color code of what color you’d like it to be.
