    Never fails, once I post the question to SO, I get some enlightening "aha" moment and figure it out. The solution:

        .container {
           border: 1px solid #DDDDDD;
           width: 200px;
           height: 200px;
           position: relative;
        }
        .tag {
           float: left;
           position: absolute;
           left: 0px;
           top: 0px;
           z-index: 1000;
           background-color: #92AD40;
           padding: 5px;
           color: #FFFFFF;
           font-weight: bold;
        }
    <div class="container">
           <div class="tag">Featured</div>
           <img src="http://www.placehold.it/200x200">
    </div>

    The key is the container has to be positioned relative and the tag positioned absolute.

    Change your positioning a bit:

    .container {
        border: 1px solid #DDDDDD;
        width: 200px;
        height: 200px;
        position:relative;
    }
    .tag {
        float: left;
        position: absolute;
        left: 0px;
        top: 0px;
        background-color: green;
    }
    

    jsFiddle example

    You need to set relative positioning on the container and then absolute on the inner tag div. The inner tag's absolute positioning will be with respect to the outer relatively positioned div. You don't even need the z-index rule on the tag div.

    you might consider using the Relative and Absolute positining.

    `.container {  
    position: relative;  
    }  
    .tag {     
    position: absolute;   
    }`  
    

    I have tested it there, also if you want it to change its position use this as its margin:

    top: 20px;
    left: 10px;

    It will place it 20 pixels from top and 10 pixels from left; but leave this one if not necessary.

    Actually just adding margin-bottom: -20px; to the tag class fixed it right up.

    http://jsfiddle.net/dChUR/7/

    Being block elements, div's naturally have defined borders that they try not to violate. To get them to layer for images, which have no content beside the image because they have no closing tag, you just have to force them to do what they do not want to do, like violate their natural boundaries.

    .container {
      border: 1px solid #DDDDDD;
      width: 200px;
      height: 200px;
      }
    .tag {
      float: left;
      position: relative;
      left: 0px;
      top: 0px;
      background-color: green;
      z-index: 1000;
      margin-bottom: -20px;
      }
    

    Another toue to take would be to create div's using an image as the background, and then place content where ever you like.

    <div id="imgContainer" style="
             background-image: url("foo.jpg"); 
             background-repeat: no-repeat; 
             background-size: cover; 
             -webkit-background-size: cover; 
             -mox-background-size: cover; 
             -o-background-size: cover;">
      <div id="theTag">BLAH BLAH BLAH</div>
    </div>

    You've got the right idea. Looks to me like you just need to change .tag's position:relative to position:absolute, and add position:relative to .container.
