Please reply with a full new code if possible.

}

#tabs ul {
  display:inline-block;
  display: -moz-inline-stack; // Firefox 2 doesn't understand inline-block but this acts the same
  zoom: 1; // Make IE7 display inline-block correctly
  *display: inline; // Only targets IE6 & IE7
  list-style-image:none;
  list-style-type:none;
  margin:0;
  padding-bottom:0;
  padding-left:50px;
  padding-right:10px;
  padding-top:10px;
}

(I tend to avoid using inline-block because it isn't supported correctly in many browsers. inline will work fine here.) - I was wrong here it must be inline-block, I edited the code above to reflect this with cross browser hacks to make sure it runs in all major browsers.

If you can set a fixed width on the ul inside #tabs, this is relatively easy:

#tabs ul {
    width: 730px;
    margin: 0 auto
}

If you can't (or don't want to) set a fixed width, you can use display: inline-block:

#tabs {
    text-align: center
}
#tabs ul {
    display: inline-block;
    padding: 10px 0 0 0
}

If you care about IE7, use:

#tabs ul {
    display: inline-block;
    *display: inline;
    zoom: 1;
    padding: 10px 0 0 0
}

See this answer for more details.

Remove float: left and padding for #tabs a,

Add display: inline-block and 1px solid #2763A5 for #tabs li

Last, #tabs ul gets text-align: center.

Hope this makes sense

change tabs to this:

#tabs {
   float: left;
   width: 50%;
   font-size: 93%;
   border-bottom: 1px solid #2763A5;
   line-height: normal;
   margin: 0 auto;
}
/*and*/

#tabs a span {
   /* remove float*/
}
