Custom background for the index page only?

I am stuck at add_custom_background.

I can change background color/image but I only want to change my index page. Currently, the changes apply on the whole page.

I want to make the changes from WP-admin.

How can I specify it to a specific page ?

Edit:

I just checked im running 3.3.1. So my version is not supported to use add_theme_support( ‘custom-background’ );

instead I want to use add_custom_background.

  if ( is_front_page() )
{
   add_custom_background();
}

Cant get it to work.

You can check in your callback function if you are an the front page.

Sample code for the theme’s functions.php:

add_action( 'after_setup_theme', 'wpse_67480_theme_setup' );

function wpse_67480_theme_setup()
{
    $bg_options = array (
        'wp-head-callback' => 'wpse_67480_background_frontend',
        'default-color'    => 'f0f0f0',
        'default-image'    => '',
    );
    add_theme_support( 'custom-background', $bg_options );

    add_theme_support(
        'custom-header',
        array (
            'width'       => 960,
            'height'      => 200,
            'flex-height' => TRUE,
            'flex-width'  => TRUE,
            'header-text' => FALSE,
            'wp-head-callback' => 'wpse_67480_header_frontend',
        )
    );
}

wpse_67480_background_frontend()
{
    if ( is_front_page() )
    {
        _custom_background_cb();
    }
}

wpse_67480_header_frontend()
{
    if ( ! is_front_page() )
    {
        return;
    }

    // create your header code here
}
