How can I horizontally center navigation menu?

Question

I'd like to center the navigation bar but I'm not sure which part of the code is problematic.

  <div align="center"><ul id="nav" class="dropdown dropdown-horizontal"><li class="hover"><a href="http://nunezmarcusstudio.com/wordpress"&gt;HOME&lt;/a&gt;&lt;/li&gt;
  <li><a name="blank">PORTFOLIOS</a>
  <ul>

Answer 1

first of all, your html is missing end div tag

more importantly, instead of , assign an id selector to your div tag and apply CSS to get the centering

for instance

<div id="wrapper"><ul id="nav">...</ul></div>

and css

body {width:100%;}
#wrapper {width:700px;margin:0 auto;}
