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 operating system chooses the closest match.

Setting the font-weight to 400 is equivalent to normal, and to 700 is equivalent to bold. A font-weight of bolder or lighter is interpreted relative to the weight of the parent object. A value of bolder for text whose parent is normal weight sets the text to bold.

Examples

The following example uses the font-weight property to change the font weight. This example uses the LI element as a selector in an embedded (global) style sheet to set the font weight to bolder:

<style>
li {font-weight:bolder}
</style>
