Doesn't this essentially put you back to the bad old days of style attributes? Sure, the "styles" you are using are much more clever and they adapt to screen sizes, etc., but you are still putting the specific style you want an element to have in the element itself and not getting any redirection. Say you have an entire application with a dozen primary pages, plus several dozen modal windows and other sub-pages. If you want to make a global change, like, "Change all the OK buttons in my entire application to have rounded corners and a gray to red gradient" then you have to go back and make a change to every button you have in the application. The whole idea with changing the CSS was that I defined a semantic CSS (e.g. "OKButton") which I used in all the places that had a common meaning, and then I could change the look of the entire application in one place.
