[BRLTTY] Computing CSS properties

[Shérab]

Dear all,

although the following question may very well be off-topic, it may also
not be completely irrelevant.

Does somebody know a way, preferably using text-mode only, to compute
the value of a CSS property at some point in an HTML document ?

This is something a sighted user can do very easily, e.g. thanks to
Firebug, but for us visually impaired users, is there some alternative
solution somebody is aware of ?

Help on this would be warmly apprecaiated.

Thanks,
Sherab.
