There are two issues here.
  1. The sig tag is wrapped in <div class="pmsig">, so the selector should be div.pmsig
  2. Your browser will silently ignore broken css, making it hard to debug - see the (untested) edits below

/* perlmonks will add style tags for you */
div.pmsig {
 font-family: lucida;
 font-size: small;
 font-style: italic;
 color: pink;
}
