Expand description
Represents the font metrics that style needs from a font to compute the
value of certain CSS units like ex
.
Fields§
§x_height: Option<Length>
The x-height of the font.
zero_advance_measure: Option<Length>
The zero advance. This is usually writing mode dependent
cap_height: Option<Length>
The cap-height of the font.
ic_width: Option<Length>
The ideographic-width of the font.
ascent: Length
The ascent of the font (a value is always available for this).
script_percent_scale_down: Option<f32>
Script scale down factor for math-depth 1. https://w3c.github.io/mathml-core/#dfn-scriptpercentscaledown
script_script_percent_scale_down: Option<f32>
Script scale down factor for math-depth 2. https://w3c.github.io/mathml-core/#dfn-scriptscriptpercentscaledown
