Questions and Answers
Q: In an HTML page's <a href="..."> tag, can you refer to a file in a different directory, or does HTML expect all files to reside in one directory?
A: On one's own WebSite, one can use the link creation syntax to point at any page, absolute or relative.
Note that <dd> has nothing to do with the <a> tag -- <dd> is used to build definition lists. (It does not mean "default directory".)
