I use zurb-foundation to maintain the layout of my website. The home page of that website is rendreded perfectly in Opera 12.14 beside some other pages. However, some pages such as this page has extra blank space on the right on Opera only. I tried to inspect element in the blank extra space, it mentioned to the html tag?!! I copied the html source into my editor (netbeans) to see if there some missing ending tags, but I did not find any of them. My website is rtl. What should cause this issue?
