Re-sizing your browser, but keeping page static?

[monkeypeach]

What is the term used to describe part of a site that collapses/adapts when re-sizing your browser.

e.g
http://(sorry, site offline)/138/index.php
This site stays static when you re-size your browser.

http://(sorry, site offline)/138/ind...ate_dir=rustic
This one expands/contracts when you adjust the size of your browser.

The template I've been modifying does the latter, but I want everthing to stay static. What do I need to do?

The most basic thing is generally to change (in your stylesheet) #mainWrapper {}
from
width: 100%;
to
width: 900px;
or whatever you want.

Individual templates may also have other elements that need to be changed.

Thanks, seems to have done the trick.
