Float right menu items not in hamburg menu for mobile

[Jacquelyn]

I have a fixed menu with a centered logo, left and right menu items. My float right menu items are showing beside the hamburger menu on responsive/mobile settings. The menu uses float: right for positioning the hamburger menu and the menu items.

<div class="topnav" id="myTopnav">
	<div class="topnav-centered">	
		<a href="index.html">JACQUELYN MCGARRY</a>
	</div>
	<div class="topnav-right">
		<a href="shop.html">SHOP</a>
		<a href="work.html">WORK</a>
	</div>
	<a href="about.html">ABOUT</a>
	<a href="contact.html">CONTACT</a>

		<a href="javascript:void(0);" class="icon" onclick="myFunction()"><i class="fa fa-bars"></i>
		</a>
</div>

<script>
function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.className += " responsive";
  } else {
    x.className = "topnav";
  }
}
</script>
