Struct MediaContext 

Source 
pub struct MediaContext {
    pub color_scheme: Option<ColorSchemePreference>,
    pub reduced_motion: MotionPreference,
    pub contrast: ContrastPreference,
    pub viewport_width: Option<f32>,
}
Expand description

Runtime view of the OS-level theme + viewport state. Passed to apply_css_with_media so @media blocks resolve consistently.

Fields§

§color_scheme: Option<ColorSchemePreference>

OS color scheme. None = unknown.

§reduced_motion: MotionPreference

User motion preference.

§contrast: ContrastPreference

User contrast preference.

§viewport_width: Option<f32>

Viewport width in CSS pixels (used for width / min-width / max-width queries). None = no width-MQ matches.
