HTML noframes Tag: Main Tips
- HTML 
noframestag was used as a fallback for browsers that did not support the <frame> element. - It had to be placed within the <frameset> element.
 - In HTML5, frames are not supported. 
<frame>,<frameset>and<noframes>have been made obsolete. 
Usage of HTML <noframes> Tags
Before it was deprecated, you could have used HTML <noframes> tags to wrap fallback content for the browsers which did not support the <frame> tag:
 Example  
<frameset cols="300, *">
  <frame src="frame_a.htm">
  <frame src="frame_b.htm">
    <noframes>
      <body>Frames element is not supported by this browser.</body>
    </noframes>
  </frame>
  </frame>
</frameset>
Usually, it was used in one of these two ways:
- To inform the user their browser does not support frames
 - To present an alternative page version with similar functionalities available
 
Tip: in HTML5, frames are not supported - however, you may use <iframe> as an alternative.
