Position box-shadow width specific width

css

I Try to add a shadow to a div element. But only to 90% of the width from the div and with margin-left from 10% . This was try

<div id="post-headline">
    <div id="post-headline-date">33.12</div>
    <div id="post-headline-title"><?php the_title(); ?></div>       
    <div id="post-headline-author"><?php the_author(); ?></div>
    <div id="shadow"></div>
</div>

CSS

#shadow{
  position:relative;
  height:5px;
  z-index:0;
  width:96%;
  left:3.7%;
  top:-6px;
  -moz-box-shadow: 0px 5px 4px #888;
  -webkit-box-shadow: 0px 5px 4px #888;
  box-shadow: 0px 5px 4px #888;
}

But it seems the percent values does not belong to the size of "post-headline". On different screen resolutions has it different values. What am I doing wrong?

Example: res1:

  • ---------------- headline
  • ------------ shadow

res2:

  • ---------------- headline
  • ----------------- shadow

UPDATE My CSS

#post-headline {
position:relative;
    background-color: #3366cc;
    color:#fff;
    left:-60px;
    height: 40px;
    width: 106.5%;
    z-index:1;
}

#post-headline:after{
  content: " ";
  position:absolute;
  width: 95.7%;
  right: 0;  
  bottom: 0;
  height: 20px;
  -moz-box-shadow: 0px 5px 4px #888;
  -webkit-box-shadow: 0px 5px 4px #888;
  box-shadow: 0px 5px 4px #888;
}

#post-headline-title {
    margin-left: 60px;
}

#post-headline-author{
font-weight:bold;
margin-left:60px;
}

#post-headline-date{
position:absolute;
margin:8px;
font-weight:bold;
font-size:12px;
}

#post-headline-triangle
{
    z-index:-1;
    left: -51.7px;
    top:-31px;
    height:45px;
    width:45px;
    background-color:#0033cc;
    transform: rotate(30deg);
    -ms-transform: rotate(30deg); /* IE 9 */
    -webkit-transform: rotate(30deg); /* Safari and Chrome */
 }

My PHP

<div id="content">
  <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
  <div id="post-headline">
    <div id="post-headline-date">33.12</div>
    <div id="post-headline-title"><?php the_title(); ?></div>       
    <div id="post-headline-author"><?php the_author(); ?></div> 
  </div>
<div id="post-headline-triangle"></div>
          ...
      <?php endwhile;endif; ?>  
</div>

Is still not working :/
