Just a heads up: below is an example with code of how I envision my interface to look, but I'm not sure if it's valid?
I've been trying to create an HTML5/CSS interface that resembles the MIRC fullscreen layout (check out the image below) and I've been searching all day, even on Stack Overflow.

What I aim for is a fullscreen interface where the user window (on the right) and chat window (on the left) have scrollbars, while keeping the message input bar at the bottom.
The ideal scenario would be achieving this using only CSS (although I can consider JavaScript if necessary), without worrying about older browser compatibility. I believe this should be doable since Mibbit has something very similar to what I want.
I'm curious if there are any frameworks or libraries that could assist me in creating such applications.
I've been experimenting with CSS all day but haven't quite figured it out yet; I reckon it's a piece of cake for someone proficient in CSS.
