WordPress 6.7 customizer extra space problem

Yes, the solution is a CSS adjustment specifically targeting the customizer's button elements in the WordPress Customizer panel. Here's what it does:

1. Create the CSS File

First, create a CSS file, e.g., customizer-fix.css, and add your CSS code to it:

 /* To remove extra spacing for customizer button  */
#customize-theme-controls .accordion-section-title button.accordion-trigger {
    max-height: fit-content;
}

This targets the button.accordion-trigger inside .accordion-section-title within the Customizer panel.

Property:
max-height: fit-content;
This ensures the button's height automatically adjusts to its content, effectively removing any unnecessary extra spacing.

2. Enqueue the CSS in Functions.php

function my_customizer_styles() {
    // Check if we are in the Customizer
    if (is_customize_preview()) {
        wp_enqueue_style(
            'customizer-fix-style',
            get_template_directory_uri() . '/css/customizer-fix.css', // Update the path as needed
            [],
            '1.0.0'
        );
    }
}
add_action('admin_enqueue_scripts', 'my_customizer_styles');

Explanation of the Code

• is_customize_preview(): Ensures the styles are only loaded in the Customizer preview.
• wp_enqueue_style: Enqueues the customizer-fix.css file.
• Path Adjustment: Make sure the path to customizer-fix.css is correct. If the file is in your theme directory, use get_template_directory_uri(). If it's in a child theme, use get_stylesheet_directory_uri().

Add the following PHP code to your theme's functions.php file or a custom plugin:

Why Use This?

In WordPress Customizer, buttons in the section titles (accordion headers) often have a fixed or unnecessarily large height. Applying max-height: fit-content; adjusts the button's height to snugly fit its content, improving the appearance and reducing unnecessary padding or spacing.

When to Use:

When there are visual issues with extra spacing around Customizer accordion section buttons.

To streamline the layout of the WordPress Customizer for a more compact and visually appealing look.
