Grid Layout is not displayed like demo

Hi,
I just installed the jux portfolio. I want the gallery to use text grid layout 3 columns. But it just look like a plain table 3 columns 2 rows with bottom vertical align.
Would you please take a look on this page? www.zantob.com/index.php/test
Did I miss something? or there is any conflict?

Thank you,
Queerine
