对于继承的父主题，您需要在子主题中添加模板行。请看这个https://codex.wordpress.org/Child_Themes

            /*
             Theme Name:   Twenty Fifteen Child
             Theme URI:    http://example.com/twenty-fifteen-child/
             Description:  Twenty Fifteen Child Theme
             Author:       John Doe
             Author URI:   http://example.com
             Template:     twentyfifteen
             Version:      1.0.0

             Tags:         light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready

您还可以使用此插件生成子主题。https://wordpress.org/plugins/one-click-child-theme/

我希望这能帮助你解决你的问题。

如果你的孩子的主题风格。css包含实际的css代码（通常是这样），您还需要将其排队。将“父样式”设置为依赖项将确保子主题样式表在其之后加载。包含子主题版本号可以确保您也可以为子主题进行bust缓存。完整（推荐）的示例如下：

add_action( \'wp_enqueue_scripts\', \'my_theme_enqueue_styles\' );

          function my_theme_enqueue_styles() 
          {

              $parent_style = \'parent-style\'; // This is \'twentyfifteen-style\' for the Twenty Fifteen theme.

                    wp_enqueue_style( $parent_style, get_template_directory_uri() . \'/style.css\' );

                    wp_enqueue_style( \'child-style\', get_stylesheet_directory_uri() . \'/style.css\', array( $parent_style ));   

           }
