Relative paths and absolute paths serve different purposes. An absolute file path is the the full URL to a file on the internet. A relative file path points to a file relative to the current page. Relative file paths are better to use than absolute file paths if possible.
When using “../ ” in a relative file path, the file path points to a file located in the folder one level above the current folder.
