XF 1.2 looking for correct CSS to style #loginbar label

[TsinJu]

I want to do some restyling to xenforo´s login Slider
I am trying to restyle this Radio Buttons.


After i get it not working with PHP, because of less knowing about it , i came up with the Idea to make the label´s a button.
Which looks in an very early stage, like that


Hover Effects will be added, matching colors etc...
Problem i have is whats the correct CSS to use?

To hide the radio buttons just inside the Slider i use

#loginBar input[type="radio"] {
    display: none;
}

To get spacing, bg-colors etc., i found this 2 css classes...

#loginBar .xenForm .ctrlUnit > dd > * > li > label {  }

and

#loginBar .ctrlUnit > dd > * > li > label {  }

Both are working.
But what´s the correct one, for the Login Slider, or am i completely wrong and someone who knows more about CSS can give me some advice?

You can use either if the both work.
