Horizontal slider GUISkin

Unity Engine
1

Hi,
I have a Gui with Sliders and i want to change the size of them when the screen width and height changes.
Ok how i can change things per script i understand but i dont understand the controles in my new GUISkin.
I assigned new thumb pictures. Now there are a few options:
Border
Left
Right
Top
Bottom
Padding
Left
Right
Top
Bottom
Margin
Left
Right
Top
Bottom
Overflow
Left
Right
Top
Bottom

But i don’t know what they do.
I Tried a little bit but don’t understand it.
I thing i understand Overflow, it’s the space were the mouse must be, isn’t it?

I hope you understand my Problem and give me an answere
Cery

Ps: sorry for bad english
