To provide text etc. to fill the right-hand side of the screen we use the following code
<HTML>
<BODY>
<P>this text is produced by<BR> right-frame.html </P>
<P>You would typically use it for your text or pictures. </P>
</BODY>
</HTML>
Copy & paste the code in NOTEPAD, saving as right-frame.html
For web pages used to provide contents for a frame, the <BODY> tag is used as normal, and as usual, needs to be closed with the </BODY> tag.
