The CSS reference
"font-weight" - css property (v. css 1)
- To specify the weight of a font.
- Initial value: normal
- The property is inherited
- HTML usage: all elements
-
Browsers that support the font-weight - property :
Possible font-weight values:
| value | Comments | CSS |
|---|---|---|
| normal | The keyword 'normal' is synonymous with the value '400'. | 1 |
| bold | The keyword 'bold' is synonymous with the value '700'. | 1 |
| bolder | Selects the next weight that is assigned to a font that is darker than the inherited one. | 1 |
| lighter | Selects the next lighter keyword with a different font from the inherited one. | 1 |
| 100 200 300 400 500 600 700 800 900 |
The values '100' to '900' form an ordered sequence, where each number indicates a weight that is at least as dark as its predecessor. | 1 |
| inherit | Will inherit the value from parent specification. | 2 |

<body style="font-size: 14pt" >
font-weight: bold; <br>

<br>font-weight: bolder; <br>
<div class="bolder" >

</body>
</html>Javascript access:
// To SET values ([o] is the target object)
[o].style.fontWeight="font-weight values"
// To GET values you must first get the computed style object
// To get that object in IE or Opera:
var cStyle=[o].currentStyle;
// To get that object in Firefox, Chrome or Safari (w3c-type):
var cStyle=window.getComputedStyle([o],null)
// To GET the property value:
var value=cStyle.fontWeight;
/* Chrome will return the keyword if a keyword for weight is set.
IE, Opera, Firefox and Safari will
return a weight number if any weight type is set.
Opera and Safari will return the keyword
'normal' if the weight is NOT set.*/
