well, to add several webpages all you need to do is use frames:
for example:
<html>
<frameset cols="25%,50%,25%">
<frame src="frame_a.htm">
<frame src="frame_b.htm">
<frame src="frame_c.htm">
</frameset>
</html>
this means there will be 3 different web pages in only one page two taking 25% of it and one taking 30% of it, if u dont get it then reply me back
