how to use 3 images in a CSS class?

[hoangvu]

Hello,

I want to create a button with css but using only a class with 3 images in it

my code below, is it right?

.mybutton{
  background-image: url(/images/middle_pic.png), url(/images/right_pic.png), url(/images/left_pic.png);
  background-position: center, right, left;
  background-repeat: repeat-x, no-repeat, no-repeat;
}

or can you give me other css style?
