Hi coders,
Please let me know how to make navigation bar of my landing page center?

#2

An easy way to center that navigation bar is by removing width:100%; and adding margin: auto to your #nav-bar CSS, like this:

#nav-bar{
  postion:fixed;
  top:0px;
  margin: auto;
}

When I click on any element of my navigation bar, navigation bar is disappeared!
