Struct style::values::computed::font::FontWeight
[−]
[src]
pub struct FontWeight(pub u16);
As of CSS Fonts Module Level 3, only the following values are valid: 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900
However, system fonts may provide other values. Pango may provide 350, 380, and 1000 (on top of the existing values), for example.
