It provides a minimal CSS foundation under 5kb and is open-sourced for community use. The framework aims to balance custom styles and usability while addressing browser inconsistencies.

How are we writing the CSS?
CSS Framework Custom Styles+
Potentially *lots* of unused CSS rules
Heavy (do we need 8k lines of CSS?)
Overwriting existing rules is annoying

Custom Styles+
Have to handle browser inconsistencies
Can’t focus on your application’s design
