Without looking at the source code, the most likely reason is that the BBC
people know what they do, and therefore they do not use `pt' as unit of
length for displaying fonts on the screen. Because that unit, designed
for printouts instead of the screen, is dependent on the font resolution;
with "Large Fonts" on Windows it is 120 ppi instead of the (1024x786)
default 96 ppi. And the (default) font resolution differs on display
resolutions and window frameworks (Macs have a default of 72 ppi, for
example).
With regard to the source code, I simply trust David Dorward's observation
and see this confirmed (they use `em' instead).

"The browser" must be Microsoft Internet Explorer 6 or older, because these
UAs are the only ones (to my knowledge) that are unable to scale _px_-sized
fonts. (In that case, it should be possible to scale the fonts on the BBC
Web site because they do not use `px'. Another possibility is to use `%'
instead of `em'.) IE 7 is going to fix at least this issue by allowing for
an Opera-style zoom of the display of Web resources.
This has nothing to do with client-side scripting. Please stop crossposting
