  41     The blue borders should coincide with light blue squares, like this:
  42     <span style="display: inline-block; background-color: lightblue; border: solid dodgerblue; width: 19px; height: 19px;"></span>.
  43     There should be none of this:
  44     <span style="display: inline-block; background-color: lightblue; width: 25px; height: 25px;"></span>
  45     or this:
  46     <span style="display: inline-block; border: solid dodgerblue; width: 19px; height: 19px;"></span>.
