How to compile with retina screen?

Good day!
Went recently on a MacBook Pro 2015 retina display.
And now if only make up on your laptop then on the monitors of 1920x1080 for example goes whole layout.
There is a second monitor of this resolution, but I don't know how to separately set the styles for the retina and do I need to do that?
Please tell me how to be and what to do?

Look for concepts such as adaptive coding or adaptive web design. You need the direction to dig.
