Tabs and IE6: how to modify space between tabs.


Hallo all.
I got this need: i have to modify the space between the tabs.
In firefox I defined in the css these classes:
.ui-tabs-nav li {
float: left;
width: 120px;
_width: 120px;
}
and
.ui-tabs-nav a, .ui-tabs-nav a span {
    margin: 0 10px;
    padding: 8px;
    width: 100px;
    _width: 120px;
    height: 35px;
    _height: 50px;
    line-height: 12px
}
The css classes are correct for firefox, but i cannot make them work
with ie6.
I can make the li larger, but I cannot make it same dimension as the
span.
any idea?
Kind regards.
