Specifies the destination address. It can be an absolute or relative URL or the name of an anchor. An absolute URL is the complete URL of a website like http://example.com/. A relative computer address points to a different directory and/or document within the constant web site, e.g. /about-us/ points to the directory “about-us” inside the root directory (/). When pointing to another directory without explicitly specifying the document, web servers typically return the document “index.html” inside that directory.
