Question

I'm trying to add a header beside my logo and center the header only

Answer 1

Have you got a code for your master-head?  If not try something like this:
HTML goes like this:
<div id="masthead">
<div id="logo">
</div>
<div id="header">
  Header Goes Here </div>
</div>
Your CSS goes like this:
#masthead {
min-width: 600px;
#logo {
float: left;
width: 200px;
#header {
margin-left:200px;
text-align: center;
If this not what you want then please post a link of your work you have already done so that basic CSS code can be given to center your text.
