The NOFRAMES element contains content that should only be rendered when frames are not displayed. NOFRAMES is typically used in a Frameset document to provide alternate content for browsers that do not support frames or have frames disabled.

When used within a FRAMESET, NOFRAMES must contain a BODY element. There must not be any NOFRAMES elements contained within this BODY element.

A meaningful NOFRAMES element should always be provided in a Frameset document and should at the very least contain links to the main frame or frames. NOFRAMES should not contain a message telling the user to upgrade his or her browser. Some browsers support frames but allow the user to disable them.

Various methods of automatically creating non-frames content exist. See Frames design guidelines: automatic no-frames content for more details.

An example follows:

<FRAMESET ROWS="*,100">
  <FRAMESET COLS="40%,*">
    <FRAME NAME="Menu" SRC="nav.shtml" TITLE="Menu">
    <FRAME NAME="Content" SRC="main.shtml" TITLE="Content">
  </FRAMESET>
  <FRAME NAME="Ad" SRC="ad.shtml" TITLE="Advertisement">
  <NOFRAMES>
    <BODY>
      <H1>Table of Contents</H1>
      <UL>
        <LI>
          <A HREF="reference/html40/">HTML 4.0 Reference</A>
        </LI>
        <LI>
          <A HREF="reference/wilbur/">HTML 3.2 Reference</A>
        </LI>
        <LI>
          <A HREF="reference/css/">CSS Guide</A>
        </LI>
      </UL>
      <P>
        <IMG SRC="ad.gif" ALT="Ad: Does your bank charge too much?">
      </P>
    </BODY>
  </NOFRAMES>
</FRAMESET>

In HTML4.0 Transitional, the NOFRAMES element is also permitted within most block-level elements. This allows authors to include content, such as navigation aids, that should only be displayed if the document is not being viewed within a frameset. Such use helps to ensure that a frame could stand on its own if bookmarked or accessed through a search engine while not burdening the frames user with duplicate content. However, most browsers do not support this use of NOFRAMES and will always display the content.
