Regarding the issue of div css layout and iframe, seniors are here to help and give me some advice. Thank you, novice,_html/css_WEB-ITnose

We are going to make a login page the day after tomorrow, made of DIV CSS layout, divided into three top, middle and tail, and the middle part is divided into center left, center center and center right. The middle left is used to place the QQ menu. I have already done this. The middle left is used to display and hide the QQ menu. The middle right is a separate page for the welcome page.

What I want to ask is the welcome page in the middle right, which is made with iframe, but I don’t know how to make the div css layout, so I don’t know how to put this welcome page in the middle right position, which is the QQ menu to the right. Below is the iframe code of my page. I would like any advice from an expert. Thank you very much!

I just don’t know how to put it in the page. The position I want

How to position the DIV, please explain clearly

The whole big div in the middle { position: relative; }
The rightmost div in the middle { position: absolute; top: 0; right: 0; }
Position it like this

center-left
