Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
@JDPorter: My comment was actually a joke. I think that hex triplets probably even predate the first CSS standard. That being said, the kata test cases cannot get changed after 500 warriors have passed the tests.
Probably a "mandatory legacy browser". ;)
