I do somewhat agree, but how would Javascript be made to create system looking controls (i.e. Unity date controls on Ubuntu, Windows like on Windows 7, etc.), without adding some extensions for DOM?

I personally dislike that CSS is turning into a miniature programming language, but I assume this is the way forward until something way better comes along and simply replaces HTML, CSS, JS. I mean its better to say width - 10 pixel than to make JS for each silly snipet like that.
