In the past weeks part of the site where the standard lay-outs are presented (see Standard lay-outs) has been fully checked on minor flaws in the stylesheet definitions (CSS).
This was also invoked because of the fact that there is one style choice added (no. 5). These style choices can be found at the top of the sidebar within the standard lay-outs.
Furthermore standard lay-outs 3 and 6 now contain the login/registration option.
