WOOF :: child_theme_url( String $file, Boolean $timestamp = true, Boolean $root_relative = true )
A preset on the WOOF::theme_url to returns a URL to a file or folder within the directory of the active theme, but forced to regard only the child theme folder. This is a highly useful method for outputting stylesheets and scripts in the head of your templates, as it can also add timestamps for the URLs by default. .
Parameters:
-
A file or folder path relative to the active theme directory.
-
Boolean $timestamp = true
Whether to add a timestamp to the end of the URL as a querystring. Note: timestamps are not added for directory paths. Timestamps help prevent aggressive browser caching by creating a URL that includes the date the file was last modified, which is generally seen as a unique request if the file has changed.
-
Boolean $root_relative = true
Whether to make the URL root-relative (removes the domain and protocol).
