Exact opposite experience. I like the newest CSS spec, and it is now supported in the vast majority of stable browsers in use.

It is an elegant approach to very common layout problems without any libraries, plugins, or javascript.

The whole point of markup and CSS is to solve the layout stuff for you. Javascript should be mainly for data transformation.

When you throw in web components and two-way data binding via object.observe, we can approach this ideal separation of concerns.
