The LINK element belongs within the HEAD element of an HTML document. It is to be used to indicate a relationship between the document and other documents or objects. Consequently a document may have any number of LINK elements.
The LINK element is empty (i.e, there is no closing
</LINK>) but takes the same attributes
as the ANCHOR element. Typically
a LINK element would be used to indicate authorship, related
indexes and glossaries, older or more recent versions, etc.
Links can also indicate the tree structure in which the
document was authored by pointing, for example, to the
"parent", "next" or "previous" documents.
<HEAD> <LINK HREF="file1.html" REL="subdocument" > <HEAD>
