Syntax
Description
This property sets the font weight that’s applied to the text content of an element.
Note that
many common computer fonts are only available in a limited number of
weights (often, the only options are normal and
bold).
Example
This style rule makes emphasized elements display with a bolder weight than that of their parent elements:
em {
font-weight: bolder;
}
Value
A font face often has descriptive
names for the different weights within that font (e.g. Regular, Light )
and as there is no accepted, universal meaning to these weight names, the
weight property values in CSS 2.1 are given on a numerical scale. The
numeric values 100–900 specify
font weights where each number represents a weight equal to or darker than
its predecessor. 400 is considered the “normal”
weight. If the specified font isn’t available in the specified weight, the
font weight will be mapped to a suitable existing value.
The following keywords can also be used for this property:
bold- is a synonym for
700 bolder- selects a font weight that’s darker than that inherited from the parent element
lighter- selects a font weight that’s lighter than that inherited from the parent element
normal- is a synonym for
400

I would argue that none of the browsers listed support font-weight to a 'full' standard, as none support the numerical scale. Currently only Firefox 3 and Webkit nightlies support numbers as values of font-weight. For more information see http://blog.gesteves.com/post/36097597/helvetica-neue-light
