Align Postbit

[gnrx]

Hello.
Now, some users comment to me that not view well the postbit info.

I think the problem is with new I.E. 9.0.

If I delete this code of my additional.css view well the info (not align, but view well the info) but if I insert this code in my additional.css the users that use IE 9 not view well the postbit.
They users, for view well the postbit need apply the compatibility to IE9.

This is the image that, the users view the postbit without mode compatibility with IE9:

Thanks and regards
