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

When you do a .5 increment while using pt. that may or may not be big enough for the browser to render larger. And then every browser renders text slightly different.
