/* Each section has a link to the next section, or to the top of the
   page. The link is inside an element (usually <p>) with
   class=skip.

   Inside the banner (<header>), the link is nearly transparent unless
   it has the focus, because that looks better. It remains visible for
   a second after it lost the focus again.

   The maximum width of a normal section is 52rem/20em minus a bit for
   the scrollbar, hence we set the maximum width of the .skip to a
   little less than 20em.

   Skip-arrows have a color depending on the section background. Give
   them a 1-pixel outline so they are visible in case they are on top
   of an image.
