 		it does not take into account the possibility of fractional viewport sizes which can occur as a result of non-integer pixel densities

 		Any viewport widths that fall between 320px and 321px will result in none of the styles being applied.

+		One approach to work around this problem is to increase the precision of the values used for the comparison. Using the example above,
