Filling sides of a centered div?

I want to fill the sides of a centered div with another div or span on each side.

I'm using margining to center the div as shown in this fiddle.

HTML

<div id='A>
  <div id='Ad'>
  </div>
</div>

CSS

#A{
  z-index: 3000;
  position: fixed;
  width: 100%;
  height:  40px;
  background: rgba(0,0,0,0.05);
}

/*
div or span to the left
*/

/*
centered div
*/
#Ad{
  z-index: 3000;
  width:  400px;
  height:  40px;
  margin-left:  auto;
  margin-right:  auto;
  border-left: solid 1px #ff0000;
  border-right: solid 1px #ff0000;
}

/*
div or span to the right
*/

How can I have a div that always takes up the remaining space on the left and another div that takes up the remaining space on the right.

Clarification:

Center column needs to be constant width. Left and Right Columns vary with the window size.

To fill space on the right and left side of your div code use and make sure you have no margin or padding on those sides.

float:right; 
float:left;

HTML: 

<div class='container'> 
<div class='left'></div> 
<div class='center'></div>
<div class='right'></div> 
</div>

CSS:

.container { overflow: hidden; margin:0; padding:0; }
.right { float: right; width: 150px; }
.center{ float: right; width:50px; margin-right: 50px; }
.left{ float: left; width: 150px; }

The margin-right of .center will fill the space accordingly.

Make 3 divs :

<div id="A"></div>
<div id="B"></div>
<div id="C"></div>
<div style="clear:both"></div>

CSS: 

 #A,#B,#C{
    float:left;
    width:10%;
  } 
  #B{
    width:80%;
  }

Here, B is you main div. It is good practice to clear when you use float property.

I would just use 3 <div>s floated within the main container

HTML:

<div id='A'>
  <div id='AdLeft'></div>
  <div id='Ad'></div>
  <div id='AdRight'></div>
</div>

CSS:

#A { overflow:auto }
#AdLeft { float:left; width:25%; }
#Ad { float:left; width:50%; }
#AdRight { float:left; width:25%; }

Here is a modified jsfiddle.

This would achieve what you want - it allows you to have a fixed width central div with left and right columns that fill up the remaining space:

HTML:

<div id="A">
    <div id="Ad">Centre</div>
    <div id="left">Left</div>
    <div id="right">Right</div>
</div>

CSS:

#A {
    z-index: 3000;
    position: fixed;
    width: 100%;
    height: 400px;
    background: rgba(0, 0, 0, 0.05);
}
/*
centered div
*/
 #Ad {
    z-index: 3000;
    width: 400px;
    height: 400px;
    margin-left: auto;
    margin-right: auto;
    border-left: solid 1px #ff0000;
    border-right: solid 1px #ff0000;
}
#left, #right {
    position:absolute;
    left:0;
    top:0;
    right:50%;
    margin-right:200px;
    background:#F00;
    height: 400px;
}
#right {
    left:50%;
    right:0;
    margin-left:200px;
    margin-right:0;
}

The key is that the margin on the left/right is half of the central column's total width, so adjust it to take into account any borders or padding.
