If unstyled body text uses the default font-size of 16px, then the
following values can and may well cause fractional pixel issues:

   .test { position: relative; font: 1em/1.4 serif;
           border: 5px solid gray; margin: 1em; color: silver; }

   .test p, .test span { color: white; border: solid 0.2em; }

line-height: 1.4 will be resolved as 16px mult 1.4 == 22.4px

border-width: 0.2em will be resolved as 16px mult 0.2 == 3.2px

There are several ways to workaround this.

I used line-height: 1.25 (resolved as 20px, which creates the usual and
normal 2px half-leading for a normal <p>)

or you may even set the font-size to 20px for .test making all tenths of
value giving whole integer pixel values.

I forgot to say in my previous email that the testcase should even
invite users to not only resize viewport width but increase/decrease
text size as well, too.

regards, Gérard
