I'll take the reward.

Please remove the position absolute.  I don't own the website nor do I have access to it.  Please pay me via below. 

#nav{
position: absolute;
}

If you do not want to remove the position absolute, you will need to add responsive CSS.
ex:
@media screen and (max-device-width: 720px)
{
  #menu{padding-left:0px;}

  #nav {
  margin-left: 200px;
  }
}
