[CSS] getting visible screen height/ width

[Guest]

Hello,

is it possible to ask in CSS for the visible screen width and height?

I want to define a tag like this

div#foo{
left: $screenwidth/2-500px;
}

if there is any chance to ask for the screen width like it´s done with
"$screenwidth" in my improvisational example.



Regards,

Martin

There are CSS3 media queries http://www.w3.org/TR/css3-mediaqueries/ but
browser support is poor.

I want to define a tag like this

div#foo{
left: $screenwidth/2-500px;
}

If you want meaningful help don't present a fantasized solution, present
the problem.

No. And even if you could, what use would it be? Browser canvas size is a
lot more useful.

div#foo{
left: $screenwidth/2-500px;
}

Try:

div#foo {
width: 500px;
left: 50%;
margin-left: -250px;
}

(think about it and you'll see why it works)
