Usage Recommendation
Use it if you have a particular purpose which you know works

  • REL: relationship to this page
  • REV: reverse relationship to this page
  • HREF: URL of related document
  • TITLE: suggested title
  • MEDIA: What media type the link applies to
  • TYPE: MIME type of linked resource

<LINK ...> is our nomination for "Most Under Supported Tag". <LINK ...> is a great idea which browser makers have largely chosen to ignore. Most of the examples on this page are from the last version of Mosaic which came out a few years ago.

<LINK ...> defines a relationship between the current page and another page or resource. Suppose, for example, that we want to establish that the home page for the current page is We would put the following <LINK ...> in the <HEAD> section:

<TITLE>Document Tags</TITLE>

The REL attribute establishes the relationship, in this case that the related page is the Home page for this web site. You can put any value you want, but certain common values have evolved (they are listed below).HREF gives the URL for the related page.

Another use for <LINK ...> (which always goes in the <HEAD> section) is to establish who is the author of the current page. To do this, we could put this <LINK ...> in the <HEAD> section:


In this case, we use REV instead of REL. REV means "the reverse relationship". That is, REV describes what the related resource would put in a <LINK ...> tag using REL. We use REV to indicate that the related entity (Miko) made this document. If we usedREL, that would indicate that this document made Miko, which isn't how it happened (my parents and God did that). HREF again indicates the URL for the related resource, in this case an email address. It is also common to put the URL of the author's personal home page.TITLE suggests a title for the resource. TITLE suggests a title for the related resource.

<LINK ...> is ignored by most browsers, which is unfortunate. (One of the only browsers in current production which does support <LINK ...> is iCab, a web browser for the Macinotsh. See their FAQ.) Mosaic was one of the few which browsers made use of <LINK ...>. Mosaic makes a sort of "quick index" bar at the top of pages which use <LINK ...>. For example, for a document whose header section looks like this:

<TITLE>Document Tags</TITLE>

<LINK REL=HOME TITLE="Idocs Home Page" HREF="">
<LINK REL=NEXT TITLE="Lines and Paragraphs" HREF="/linepar/">
<LINK REL=COPYRIGHT TITLE="copyright info" HREF="copyright.html">
<LINK REL=STYLESHEET TITLE="style sheet" HREF="html.css">


Mosaic will put a link bar at the top of the page:

Mosaic even recognizes some of the more common values for REL and REV, and uses appropriate icons for them. These are the values it recognizes:

Beginpicture of begin LINK icon
Previous picture of previous LINK icon
Nextpicture of next LINK icon
Endpicture of end LINK icon

Putting a link bar on the page is not the only use for <LINK ...>. Browsers which use stylesheets can refer to a central style page using REL. Corporate intranets can use <LINK ...> to build site maps. <LINK ...> can be a useful tag for many purposes; hopefully browser makers will start utilizing its potential.
