This is an abomination. Do we honestly need a "framework" to use the background-color and float properties? Not to mention that the design here is very poorly executed, and as someone else mentioned the responsiveness doesn't even work. I'm not trying to be a hater or a downer, I just can't believe that this is the state of web design right now. As Gob would say, "COME ON!"
Please, be constructive instead of just dismissive. A nasty tone doesn't help anyone nor does it encourage trying new things.
I do apologize for the harshness, especially if it offended people, and I'm all for trying new things, but something like this should absolutely not be up on the popular page of hacker news. This is an amateur attempt at a framework that was very poorly done. Is that honestly deserving of more than 100 upvotes?
