    The get_custom_header_markup() function in WordPress is used to retrieve the markup for a custom header. Here's a detailed explanation of its functionality and a sample usage:

    1. Function Signature:

      get_custom_header_markup(): string
    2. Purpose:

      • The primary function of get_custom_header_markup() is to retrieve the HTML markup for a custom header in a WordPress theme.
    3. Description:

      • When this function is called, it returns the HTML structure for the custom header. This is particularly useful for theme developers who need to insert a custom header into their theme layout.
      • The function will always return the container <div> for the custom header, especially within the Customizer preview, ensuring that theme customizations can be previewed live.
    4. Return Value:

      • The function returns a string that contains the HTML markup of the custom header.
      • If the function executes successfully, it will return the markup for the custom header. If there is no custom header or if the function fails, it may return an empty string or a default value.
    5. Sample Usage:

      // Check if the theme supports a custom header
      if ( current_theme_supports( 'custom-header' ) ) {
          // Get the custom header markup
          $custom_header_markup = get_custom_header_markup();
          // Output the custom header markup
          echo $custom_header_markup;

      In this example, the code checks if the current theme supports custom headers. If it does, the get_custom_header_markup() function is called to retrieve the markup for the custom header, which is then outputted (echoed) where needed in the theme.

    This function is a part of the WordPress template system and allows for dynamic rendering of custom headers, making it easier for theme developers to integrate this feature into their themes.
