iFrames Options

[rawoarbby]

I really don't understand iframes; but it would be so much easier to actually change the layout than going to EVERY single page and changing the layout there;
anyone willing to help?

i understand about the code
<iframe frameborder="0" width="500" height="5000" src="http://yousite .com/index.html" name="Content" allowTransparency="true" scrolling="no" align="top" style="position:absolute; top:450px; left:206px"></iframe>

but i don't really underztand the rest;
am i suppose to put the iframe code in every single page that i want the same layout in?
and
am i suppose to have a separate iframe code for the sidebar and the updates?
please help
