Always on the lookout for a quality (low/no js) CSS framework. One that uses sane structural paradigms and doesn't leave a build beholden to 3rd party documentation / questionable design decisions. One that is straightforward to pull back / strip out when the time comes. One with reasonable overheads (branding, download size, etc). And with all that in place - one that handles forms / browser chrome well. Yet to find it, but this looks like it comes pretty close. I'm willing to try it.
That said, I had performance issues on the site in Firefox. Very noticeable when switching between dark / light mode. Not sure if anyone else saw the same?
