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.

To convert these strings to numeric equivalents, use the read-only fontWeight property.

Examples

The following examples use the font-weight attribute and the font-weight property to change the font weight.

This example uses li as a selector in an embedded (global) style sheet to set the font weight to bolder.

<style type="text/css">
li { font-weight:bolder }
</style>

This example uses inline scripting to set the font weight to bolder when an onmouseover event occurs.

Code example: http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/fontWeight.htm


<p style="font-size:14" onmouseover="this.style.fontWeight='bolder'">
