pub const COMPACTNESS_ATTRIBUTE: &str = "data-compactness";Expand description
The root-element attribute a reader’s row-packing choice is written to.
compactness_css emits the compact arm of this attribute on :root, so
setting data-compactness="compact" on <html> densens the rows and
removing it hands the choice back to the comfortable default. Like
DENSITY_ATTRIBUTE, it belongs to the device rather than the account.
