CSS Font Size .5 Increments

Question

In CSS are you allowed to use .5 increments i.e

font-size: 8.5pt;

Can\'t see the difference between font-size: 8pt and font-size: 8.5pt

Answer 1

A half point is a very small amount. Without zooming your screen, you likely will never see the difference. Nonetheless, the software IS calculating it and displaying it as best as your resolution allows.
