exactly so inside of this

.nav li a {
    float:left;
  height:50px;
  width:50px;
  padding:10px;
  background-color:#f00;
  border: 2px solid #ff0;
}
.nav li a:hover #a{
     border: 2px solid #000;
}

how can i change the border value of

.nav li a {
    float:left;
  height:50px;
  width:50px;
  padding:10px;
  background-color:#f00;
  border: 2px solid #ff0;
}

inside of

.nav li a:hover #a{
     border: 2px solid #000;
}
