Hi there everyone,

First, please let me tell you that I've looked all of the example layouts in the site, but I cannot find any one suite my layout.

I can see that all layouts described, suppose on 3 columns, we have to know the width of 2out 3 columns (whether in % or px) in order to create the completed 3 columns with flexibility.

Anyway, according to my wanted layout,
I only know the width of the middle columns which is 1007px + set it in the middle of screen.
The other ones on side directions, I would like to let it expand to the end of screen.


If anyone give me an advice, that would be great and thank you.
I would wait for an answer.

EDIT: add more one condition 'set in the middle of screen'
