« SVG Attribute reference home
The font-weight attribute refers to the boldness or lightness of the glyphs used to render the text, relative to other fonts in the same font family.
As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet, see css font-weight for further information.
Usage context
| Categories | Presentation attribute |
|---|---|
| Value | normal | bold | bolder | lighter | 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 | inherit |
| Animatable | Yes |
| Normative document | SVG 1.1 (2nd Edition) |
Keyword meanings
- bold is equivalent to 700
- normal is equivalent to 400
- bolder and lighter will instruct the browser to use a thicker or thinner font-weight (respectively) compared to the current element's parent. Child elements will inherit the resulting calculated font weight.
Cautions
Many fonts only have 400 and 700 weights available. Available weights may vary font-to-font.
Example
css
p.normal {font-weight:normal;}
p.thick {font-weight:bold;}
p.thicker {font-weight:900;}
html
<p class="normal">This is a paragraph.</p> <p class="light">This is a paragraph.</p> <p class="thick">This is a paragraph.</p> <p class="thicker">This is a paragraph.</p>
