Use `box-shadow` instead of `border` for interface element
When we need to show the limitations of an element (a page for example) we use a 1px border.
Which will offset things by 1px.
Using box-shadow will be easier as it will keep things at their real size:
box-shadow: 0 0 0 1px rgba(0, 0,0,0.2);
will be more accurate for the transition between screen and print.
