Support for larger/custom media queries/breakpoints

apart from the resized containers that we get when using the large screen media query (Activate 1200px “Large Screen” media query), is it possible to have 2 different style sheets, one for wide screen desktop, and one for “standard” screens and landscape tablets ?

I would like to have bigger sizes (text, images, etc) for large screens and smaller ones for standard screen sizes and landscape tablet.

Should I add a specific style sheet in the header ?

Thanks.
