Would have gotten the point across better to just inline the CSS source on the landing page, or linking to the CSS file, instead of having to download a ZIP.
I agree. The way they're presenting this is truly burying the lead.
I'd suggest something along the lines of "Here are 135 lines of CSS that we like, and that we feel might be reusable".
It took me an inordinate amount of time to figure out that this was what was being presented to me here. Calling it a "Minimalist Framework" certainly pushed some buttons for me, because I'm all for minimalism, but militantly opposed to almost everything that calls itself a "framework", so as soon as I saw this, I had to go on a mission to figure out what this was, and why they put these two words in a sentence, and was then rather underwhelmed.
Thanks for the feedback.
Edit: I've reworded the page a bit based on this and other feedback too.
