Talk:Standardize classnames and layout to facilitate theming
I like the way this is going. Naturally I will only comment on the bits I don't completely like ;-)
I still don't get why "Eliminate span.maincontent" is a good idea, but then I already explained my reasoning in MDL-34723.
On an unrelated note, I recommend reading some articles like http://css-tricks.com/efficiently-rendering-css/ and http://boblet.tumblr.com/post/34751669/tips-for-css-performance and the classic https://developer.mozilla.org/en-US/docs/CSS/Writing_Efficient_CSS that they both link to. Hence, some parts of your recommendations worry me a bit, like the one to always prefer classes to ids.
