Added a footer and a dotted line to separate articles. Neither of these developments is particularly exciting. But, the footer does include the following:

<?php
  define("QUOTE1", "Things should be made as simple as possible, but not simpler.");
  echo QUOTE1;
?>

This might seem needlessly complicated, but I wanted to echo a variable, because it will gradually develop into a random "quotation" module. (The above is attributed to Albert Einstein.)
