Micro is a microscopic CSS and Ajax framework for Phosphorus Five. Micro builds upon a container/row/col structure,
and is such quite similar to Bootstrap CSS, but is significantly smaller in size, and created around the "flexbox CSS model".
Micro is easily skinned, due to clever use of CSS variables.
Micro is automatically installed when you install Phosphorus Five.
Micro is free and open source software, and licensed under the terms of the Gnu Public License, version 3, in addition to that a proprietary enabling license is available for a fee.
