When I started Picnic CSS[1] there were few CSS libraries out there and the ones that were available were severely lacking. They didn't have either :hover or :active states, no transitions, etc.
Now with new libraries or modern versions of those, including Semantic UI, I wonder whether it's time to stop supporting it and switch to one of those. They are still different but with somewhat similar principles (at least compared to others) such as the grid: <div class="flex two"><div></div><div></div></div>.
What I want to say, kudos. As I see jlukic answering some questions, how do you find the time/sponsorship to keep working on it? Is it a personal project, company project, funded through some external medium, etc? I see there's a donate button, does people contribute there a lot?
