Iframes

Now iframes can be confusing to understand at first. it took me like 3 months to finally understand them. So what you have a layout you usually have it set up like this:
Header Codes ( [images] [css codes] ect.)
Your Content (news, graphics, tutorials, ect)
Footer Codes ( whatever you have. You might now have any.)

Now where your content would go you need to put this code:

<iframe name="main" src="NEWS/OTHER MAIN PAGE" frameborder="0" width="890" height="2000" allowtransparency="yes"></iframe> Now explaining the code.
The name you will use when you make links. you links will be coded like this: <a href="" target="main">Link Name</a> scr="" that is where you will put the cutenews url i gave you. It is just the main page you want your iframe directed to.
Frameborder, thats simple enough, if/how you want the border.
Width and hight is how big you want your iframe to be.
Allowtransparency is so you can set your other pages to have a transparent background.
