php - 实时 CSS 未生成

Question

我在这里做错了什么，为什么 live css 不工作。

我从这里引用了https://codex.wordpress.org/Theme_Customization_API但它对我不起作用

        //adding nav color controlller
         $wp_customize->add_section('nav_color',array(
           'title'    => __('Style Navigation','dgthemecustomizer'),
           'panel'    => 'DG_COLOR_STYLING',
           'prority'  => '10'
         ));

         $wp_customize->add_setting('nav_color',array(
              'default'   => '#FFFFFF',
              'transport' =>  'refresh'
         ));

         $wp_customize->add_control(
                new WP_Customize_Color_Control($wp_customize,'nav_color',array(
                    'label'      => __( 'Navigation Background', 'DG_theme_customizer' ),
                    'section'    => 'nav_color',
                    'settings'   => 'nav_color',
                  'context'    => 'Navigation Background'
              ))
          );

        //function for making custom style work

        function custom_color_scheme(){
        ?>
            <style type="text/css">
               header{
                 background: #<?php echo get_theme_mod('nav_color');  ?>;
               }
            </style>
        <?php  }

        add_action('wp_head', 'custom_color_scheme');
       ?>

使用wp-color-picker-alpha.min.js 从github下载文件，通过wp_enque使用。 https://github.com/23r9i0/wp-color-picker-alpha/blob/master/src/wp-color-picker-alpha.js
