This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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.
Note: As a presentation attribute, font-weight also has a CSS property counterpart: font-weight. When both are specified, the CSS property takes priority.
You can use this attribute with the following SVG elements:
<svg viewBox="0 0 200 30" xmlns="http://www.w3.org/2000/svg"> <text y="20" font-weight="normal">Normal text</text> <text x="100" y="20" font-weight="bold">Bold text</text> </svg>
| Value | normal | bold | bolder | lighter | <number> |
|---|---|
| Default value | normal |
| Animatable | Yes |
For a description of the values, please refer to the CSS font-weight property.
