How to center a horizontal navigation bar

Question

I am having trouble centering my navigation bar.

This is the example nav bar I am working with

<style>
/* Begin Navigation Bar Styling */
#nav {
  width: 100%;
  float: left;
  margin: 0 0 3em 0;
  padding: 0;
  list-style: none;
  background-color: #f2f2f2;
  border-bottom: 1px solid #ccc; 
  border-top: 1px solid #ccc; }
#nav li {
  float: left; }
#nav li a {
  display: block;
  padding: 8px 15px;
  text-decoration: none;
  font-weight: bold;
  color: #069;
  border-right: 1px solid #ccc; }
#nav li a:hover {
  color: #c00;
  background-color: #fff; }
/* End navigation bar styling. */
</style>

but as seen, the navigation bar is not centered.

I have tried using auto margins but it doesn't work. How do I go about fixing this?

Answer 1

Add text-align:center; to #nav

Remove float:left; and add display: inline-block; to #nav li

Change to this:

#nav {
    width: 100%;
    float: left;
    margin: 0 0 3em 0;
    padding: 0;
    list-style: none;
    text-align:center;
    background-color: #f2f2f2;
    border-bottom: 1px solid #ccc;
    border-top: 1px solid #ccc;
}
#nav li {
    display: inline-block;
}
