So a pixel is a solid angle, what a completely abysmal definition!

my computer tells me its screen has W times H pixels and these
are not solid angles!

... hard for me to understand the motivations behind that
amazing CSS3 definition!

thanks for the info! this opens the veil for me on the
wild world of web design; which after all is know dominated
by money and not by the spirit of the metric system from
the French Revolution!
