The property is read/write
for all objects except the following, for which it is read-only:
currentStyle.
The property has a default value of
normal. The Cascading Style Sheets (CSS) attribute is
inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see about dynamic properties.
remarks keywords for font-weight values are mapped to specific font variations depending on the fonts that are installed on the user's computer. in many cases, the user cannot see the difference between different font-weight settings because the system chooses the closest match. setting the font-weight to 400 is equivalent to normal, and to 700 is equivalent to bold. an font-weight of bolder or lighter is interpreted relative to the parent object's weight. a value of bolder for text whose parent is normal sets the text to bold. microsoft® internet explorer 4.0 supports only normal and bold. internet explorer 3.0 supports the font-weight attribute through the font attribute.
