是的。默认情况下，我可以通过以下方式显示它：

<?php
add_action(\'customize_controls_print_styles\', function()  {
?>
    <style id="custom-css">
        #sub-accordion-section-custom_css .description {
            display: block !important;
        }
    </style>
<?php
});

您将需要get_section 的方法$wp_customizer class. 像这样：

add_action( \'customize_register\', \'wpse261932_change_css_title\', 15 );

function wpse261932_change_css_title () {
  global $wp_customize;
  $wp_customize->get_section(\'custom_css\')->title = __(\'Additional CSS. Be careful!\', \'textdomain\');
  }
