Re: Question about px: Relative size?

For accessibility purposes, pixels should be considered non-scalable,
and should not be used.

I find the reference to their being relative confusing.  It comes about
because printer resolutions are much higher than screen resolutions, so
multiple device pixels have to be used for a single px.

In the relative sense, a px is about 1/800th of the screen width and
rounded to be an integral multiple (or exceptionally sub-multiple) of
the device pixel size.

However, I would argue that the more common definition of being about
1/96th of an inch rounded to a physical pixel is more a physical size.
