Optimised for 770 pixels but also liquid - Possible?

[Calculus]

I'm learning positioning with CSS right now and it's tricky to say the least.

The usability fella Nielson suggests this as far as page width -

'Optimised for 770 pixels, but with a liquid layout that works at anything from 620 to 1024 pixels'.

Would the above be easy to achieve using CSS?

Yes.

Optimised for 770 pixels means that the page should look acceptable at that resolution, but if you have higher resolution the design must be flexible and also look good at higher res.

There are different ways of achieving this. Lately a javascript has started to popup here and there that selectively uses a css or another based on browser width. But it can be achieved with css alone.
