/* ============================================================
   SPHINX SHARED HEADER AND FOOTER STYLES
   Used by every page on www.sphinx.pl, together with
   /shared/site-chrome.js, which inserts the header and footer.
   Change the header or footer here and in site-chrome.js only.
   The colours and spacing are set on the header and footer
   themselves, so these styles work with any page's own CSS.
