I know this off topic, but I consider you guys as expert coders 
I have modified an smf theme to look like my joomla site
www.vibez.co.uk/forum
.
I'm wanting to make the template have a min and max width.
I have included the line below in the css
#bodyarea,.okvir{
min-width: 750px;
max-width: 950px;
width: expression(document.body.clientWidth > 950? "950px": "auto" );
This works fine in Internet explorer, but in firefox the forum stays at 750px wide all the time. Any idea why?
