I have inspected the document, and I don't find any font-size selector to modify font-size of buttons ... where are they ? :P

The computed style for one of them is:

1. -webkit-background-clip: padding-box;
2. background-attachment: scroll;
3. background-clip: padding-box;
4. background-color: #EEE;
5. background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#FDFDFD), to(#EEE));
6. background-origin: padding-box;
7. border-bottom-color: #CCC;
8. border-bottom-right-radius: 9px;
9. border-bottom-style: solid;
10. border-bottom-width: 1px;
11. border-left-color: #CCC;
12. border-left-style: solid;
13. border-left-width: 1px;
14. border-right-color: #CCC;
15. border-right-style: solid;
16. border-right-width: 1px;
17. border-top-color: #CCC;
18. border-top-right-radius: 9px;
19. border-top-style: solid;
20. border-top-width: 1px;
21. color: #444;
22. cursor: pointer;
23. display: inline-block;
24. font-family: Helvetica, Arial, sans-serif;
25. font-weight: bold;
26. height: 37px;
27. margin-bottom: 0px;
28. margin-left: 0px;
29. margin-right: 0px;
30. margin-top: 0px;
31. padding-bottom: 0px;
32. padding-left: 0px;
33. padding-right: 0px;
34. padding-top: 0px;
35. position: relative;
36. text-align: center;
37. text-decoration: none;
38. text-shadow: #F6F6F6 0px 1px 1px;
39. width: 151px;

No font-size!!! :(

Thank you !
