Responsive css background images

Question

I have a website (g-floors.eu) and I want to make the background (in css I have defined a bg-image for the content) also responsive. Unfortunately I really don\'t have any i

Answer 1

If you want the same image to scale based on the size of the browser window:

background-image:url('../images/bg.png');
background-repeat:no-repeat;
background-size:contain;
background-position:center;

Do not set width, height, or margins.

EDIT: The previous line about not setting width, height or margin refers to OP's original question about scaling with the window size. In other use cases, you may want to set width/height/margins if necessary.
