pub const MIN_CEILING: u16 = 64;Expand description
The widest a column’s floor may be, in ch.
A bound so a webview can name every floor as a class from a fixed ladder:
a container condition cannot read a custom property, so the length a
column hides its contents under has to be written into the stylesheet.
Wider than any column the tree declares, and a column wanting more is a
Width::Fill with this as its floor.
