how many pixels a *floating container* should be grown or shrunk (the default
is 10 pixels). The ppt argument means percentage points and specifies by how
many percentage points a *tiling container* should be grown or shrunk (the
default is 10 percentage points). Note that +resize set+ will only work for
floating containers.
default is 10 percentage points).
Notes about +resize set+: a value of 0 for <width> or <height> means "do
not resize in this direction", and resizing a tiling container by +px+ is not
implemented.
It is recommended to define bindings for resizing in a dedicated binding mode.
See <<binding_modes>> and the example in the i3
