font-weight
Defines the font weight. Numerical font weights do not render as expected in e-mail. See Notes below.
Usage:
style="font-weight: normal|bold;"
NOTES:
Only the normal and bold values work when used in e-mail.
Numerical font weights are interpreted from 100 - 300 as lighter text, 400 - 600 as normal text,
and 700 - 900 being rendered as bold text. The lighter and
bolder values render in e-mail as normal and bold text, respectively.
Interesting note:
In Outlook '07, a font-weight of 600 rendered bolder than the 700, 800, and 900 weights.
