UI Tabs Font Problem ...

The problem is: When I am using Tab Control, the text inside the control is very very big and not using default size and this is all Chinese char, but English or digital is small correctly, how can I solve this problem, I am just using in base.css, which is my web page default font size.

  4. margin-top: 0px;
  5. margin-bottom: 0px;
  6. margin-left: 0px;
