Implementations

impl RestyleHint

pub const RESTYLE_SELF: Self = _

Do a selector match of the element.

pub const RESTYLE_PSEUDOS: Self = _

Do a selector match of the element’s pseudo-elements. Always to be combined with RESTYLE_SELF.

pub const RECASCADE_DESCENDANTS: Self = _

pub const RESTYLE_CSS_TRANSITIONS: Self = _

pub const RESTYLE_STYLE_ATTRIBUTE: Self = _

Don’t re-run selector-matching on the element, only the style attribute has changed, and this change didn’t have any other dependencies.

pub const RESTYLE_SMIL: Self = _

Replace the style data coming from SMIL animations without updating any other style data. This hint is only processed in animation-only traversal which is prior to normal traversal.

impl RestyleHint
