You need to set a width to your div and add the margin css property shown below

 <div style="width:500px; margin:0 auto;">
     Your content
 </div>

If you set width to 50%, then left position to 25% -> that way, your div will always be centered, no matter if you resize parent object.

#header {   
    width: 50%;
    left: 25%;
}

<div id='test' class='#header'>My content goes here</div>
