Resolves the percentage.

source

pub fn percentage_relative_to(&self, basis: Length) -> Length

Convert the computed value into used value.

source

pub fn maybe_percentage_relative_to( &self, container_len: Option<Length> ) -> Option<Length>

If there are special rules for computing percentages in a value (e.g. the height property), they apply whenever a calc() expression contains percentages.

source

pub fn clamp_to_non_negative(self) -> Self

Returns the clamped non-negative values.

source§

impl LengthPercentage

source

pub fn normal() -> Self

Return the normal computed value, which is just zero.

impl MallocSizeOf for LengthPercentage

source§

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
