> Normalize.css is modular

That is a strong claim given that the "modularisation" is realised adding banner comments in the CSS. I think it would had been better to have separate @import'ed files. Those worried about performance could use minificators while other, like me, could just use the parts they are interested in, in my case

    @import 'normalize.css/html5-fixes.css'
    @import 'normalize.css/html5-defaults.css'
