I think what was meant is that the creator of the site has specified 1em
to be equivalent to 10px.

Actually, all modern browsers (Firefox, IE, Opera, Safari, Konqueror)
start with a "factory setting" font-size of 16px, meaning 1em translates
to 16px (where pixel is defined as in the CSS2 standard ). I think this
is why the question was originally raised; if the page in question was
starting from the default browser settings, one would expect 1em to equal

1 point is (approximately) 1/72 of an inch. It's a centuries-old printers
measure, and how it translates to relative length units such as pixels is
entirely down to how the browser maps real-world measurements like pt, in
and cm to the output device - see the discussion of "absolute length
units" at .
