That's where you are wrong. px are not fixed size, they depend on the screen
resolution. While this was ok in a world where all the available display
hardware was in the range of 90 to 125dpi, this is not the case anymore.
Some smartphones, and now some computers, have a pitch as high as 300dpi.
This makes a 12px font ridiculously small. On the other hand, using pt keeps
the font size the same for all these displays (the physical size, in inches
or centimeters).
em is a relative unit. This solves a different problem.
