jQuery Forum

I wrote a script that works wonders in Chrome, but it does not work in Opera and Firefox. I'm new in js. Prompt in what could be wrong?

1. $(function() {
2.     $("#question_tab").hover(function() {
3.         if ($("#question").css("left") == "100%")
4.             $("#question").css("margin-left", "-50px");
5.     }, function() {
6.         if ($("#question").css("left") == "100%")
7.             $("#question").css("margin-left", "-38px");
8.     });
9. 
   
10.     $("#question_tab").click(function() {
11.         if ($("#question").css("left") == "100%") {
12.             $("#question").animate({
13.                 marginLeft: "-380px",
14.                 left: "50%"
15.             });
16.         } else {
17.             $("#question").animate({
18.                 marginLeft: "-38px",
19.                 left: "100%"
20.             });
21.         }
22.     });
23. });

I think problem is in checking - if ($("#question").css("left") == "100%")
