{{SVGRef}}

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` can be used as a CSS property. See the CSS {{cssxref("font-weight")}} property for more information.

You can use this attribute with the following SVG elements:

- {{SVGElement("text")}}
- {{SVGElement("textPath")}}
- {{SVGElement("tref")}}
- {{SVGElement("tspan")}}

## Example

```css hidden
html,
body,
svg {
  height: 100%;
}
```

```html
<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>
```

{{EmbedLiveSample("Example", "200", "30")}}
