get_stylesheet_directory() │ WP 1.5.0

Gets the absolute path to the child theme or parent theme (if the child theme is NOT used). Does not contain a trailing slash /.

This function points to the folder where the current theme's stylesheet file is located.

For example: if the parent theme is currently activated, we get the path to it, and if the child theme is activated, we get the path to the child theme.

Thus, this function can be used in the parent theme to get the path to the child theme when it is activated.

Use get_template_directory() when you need to get the path to the parent theme from the child theme.

Use get_stylesheet_directory_uri() when you need to get the URL, not the path.

Uses: get_stylesheet(), get_theme_root()
Used By: get_theme_file_uri()
