CSS Font Size .5 Increments
css, font-size
Solution
Point values are really only for print CSS.
Quoting Chris C:
A point is a unit of measurement used for real-life ink-on-paper typography. 72pts = one inch. One inch = one real-life inch like-on-a-ruler. Not an inch on a screen, which is totally arbitrary based on resolution.

The W3C Tips page suggest avoiding them for screen:
The so-called absolute units (cm, mm, in, pt and pc) mean the same in CSS as everywhere else. A length expressed in any of these will appear as exactly that size (within the precision of the hardware and software). They are not recommended for use on screen, because screen sizes vary so much. A big screen may be 60cm (24in), a small, portable screen is maybe only 8cm. And you don't look at them from the same distance.

Problem
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
