CSS calc width and height values

Question

How can I calc, using css, the screen height and use the returned value for the width calculation? is it possible at all?

myClass{    
    height: calc(50% - 33.5px);
    width: heightReturnedValue*1.3
}

Answer 1

Yes, in css there is a thing called vh (viewport height) and vw (viewport width). The viewport is the screen.

myClass {    
  height: calc(50% - 33.5px);
  width:  calc(100vh * 1.3);
}
