HTML CSS Nav get my margin-top of Table

I have a SideNav which is position: absolute; and is fill all the left side of screen and my table is on the middle of screen, but if I want to apply a margin-top:50px; the SideNav get it too.

If I remove the position it works but it can't fill all the left side anymore.

I don't know why it does that, thanks for help.

Solution

  • Instead of applying margin-top: 50px; to your <body> element, apply:

    padding-top: 50px;

    also, in addition to declaring position: absolute for #navigator, you should, ideally, provide explicit co-ordinates.

    e.g.

    #navigator {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  color: #0585e1;
  background-color: #354256;
}
