These sites have all broken because of the way browsers handle new css properties, and by that I mean the -browser prefix. Web developers see this new shiny feature that either makes the page prettier, or easier to create, of course they'll use them. If browser developers really wanted web developers not to use these properties they would have to be enabled, manually, per browser. That would allow people to create implementations and test them, but stop prefixes getting onto the general web. Instead we are left with many browsers (i.e. not chrome) being forced to implement each others prefixes, and to a lesser extend JS libraries.
