#### This PR includes [JUX2] [16]: https://github.com/joomla/joomla-cms/pull/2117 
This change should be viewed together with the changes [16] brings and how it looks.
Also because of canges to many same css classes, there would be conflicts after [16] gets merged, if this one was completely separated.
 [JUX2] [16] https://github.com/joomla/joomla-cms/pull/2117 should be merged first!
