How can I stretch my nav bar to fit width of browser, wothout scroll bar?

[suavedesign]

How can I make a nav bar stretch the entire width of the browser (every size browser, even when zoomed in or out) without getting a horizontal scroll bar?
The url to my site is www.accupresh.com. I have a nav bar that I want to be stretched to fill the entire width of the browser, no matter what the size of the screen. How can I do that without getting a horizontal scrollbar at the bottom?
Thanks!

I managed to make it stretch on the right side, by adding padding, and then

overflow-x:hidden;

overflow-x:hidden; to the body.
But how can I make the left side stretch? Adding padding would just push over all the tabs.

Is something like this?

.my-nav-bar {
    width: 100%; /* the parent must have 100% either */
    overflow: hidden; /* hides overflow */
}

Wrap your nav div in a wrapper div. Set the wrapper div width:100% set the nav div to the width of the page content than margin:0 auto; :

.nav_wrapper{
  width:100%;
  background-color: #FFF; //Change this to the background color of your nav bar
}

.nav_bar{
  width: 800px; //Change this to the actual width of the page content
  margin: 0 auto;
}



<div class="nav_wrapper">
  <div class="nav_bar">
    <ul id="nav_menu">
      <li class="page_item page-item-120 current_page_item"><a href="http://www.accupresh.com/">Home</a></li>
