I've dropped it accidentally with my last commit. Furthermore I moved
the data-feed-id definition to the article element and dropped multiple
references of the feed id. That's similar to what I've done before with
the data-item-id in 3dae99ac.
The article element holds the information whether a feed is disabled now.
Now it is shown if a feed had errors while updating.
Unified the page-counters before.
This makes processing of counters in javascript way more easier. The minimum
required browser versions for the needed CSS3 selectors are IE9, Firefox 3.5
and Chrome 5. Confirmed working with IE9, Firefox 24.6, Chrome 36, Mobile Safari
on iOS6.
An unintended side effect of CSS brackets is that theme designers are able to
implement there idea of brackets.
