Sorry, I know that's exactly how my comment reads. However, given how many CSS frameworks are posted to HN everyday I think it's reasonable to expect at very least the demo to be mobile friendly, especially if it's touting material design.

I was not referring to yours as you gave constructive feedback (and indeed, mobile version needs work). I'm talking about the blanket dismissals.

Honestly that's on par for the course for anything visual/design related on HN.
