Prevent a specific child div from expanding the parent div

I'm currently developping a website and encountered a problem with CSS.

I have a parent div containing 2 or more children: one containing the name of a user that sits on top of the other children, and just below 1 or more side by side divs which display items owned by the user.

At the moment it works fine, but if the user's name (top div) is larger than the total width of the divs below, it will expand the parent div.

I'd like to only allow the bottom divs to expand the parent div and make the title div use the full parent div's width without being able to make it larger.

I created a fiddle about it: http://jsfiddle.net/mLxjL/2/

HTML:

<div class="matches">
    <div class="match-container">
        <div class="user-match-container">
            <div class="match-owner user">You</div>
            <div class="match">
                <div class="thumbnail">
                    <img class="image-container" src="img-path">
                    <div class="thumbnail-count">2</div>
                </div>
                <div class="item-name">The Zeppelin of Consequence (Trading Card)</div>
            </div>
        </div> <span class="arrow">→</span>	
        <div class="user-match-container">
            <div class="match-owner friend">PfaU- [W] King Arthurs Gold</div>
            <div style="clear:both;"></div>
            <div class="match">
                <div class="thumbnail">
                    <img class="image-container" src="img-path">
                    <div class="thumbnail-count">2</div>
                </div>
                <div class="item-name">The Lost Hobo King</div>
            </div>
        </div>
    </div>
</div>

CSS:

.match-container:before, .match-container:after {
    content:"";
    display:table;
}
.match-container:after {
    clear:both;
}
.match-container {
    border:1px solid #666;
    background-image:url('img/stripes.png');
    border-radius:5px;
    padding:10px;
    margin:10px;
    float:left;
}
.match {
    width:112px;
    float:left;
    margin: 0 2px;
}
.match .image-container {
    width:112px;
    height:130px;
    display:block;
}
.match .item-name {
    line-height:12px;
    font-size:10px;
    margin-top:4px;
    text-align:center;
    height:24px;
    overflow:hidden;
    clear:both;
}
.match-container .arrow {
    float:left;
    position:relative;
    top:70px;
    margin:5px;
}
.match-owner {
    line-height:14px;
    font-size:12px;
    margin-top:4px;
    text-align:center;
    height:14px;
    overflow:hidden;
    margin-bottom:4px;
    border:1px solid #666;
    background-image:url('img/stripes.png');
    border-radius:5px;
}
.match-owner.user {
    background-color:green;
}
.match-owner.friend {
    background-color:red;
}
.thumbnail-count {
    position:relative;
    top:-24px;
    margin-bottom:-24px;
    font-size:16px;
    font-weight:bold;
    border-top:1px solid white;
    border-right:1px solid white;
    border-top-right-radius: 7px;
    font-size:18px;
    background: rgb(160, 160, 160) transparent;
    background: rgba(160, 160, 160, 0.70);
    padding: 0 4px;
    float:left;
}
.user-match-container {
    float:left;
}

Is it possible to do this without using JavaScript?

You can use Absolute positioning

FIDDLE

position:absolute;
top:0;
left:0;
width:100%;

and on the container div :

padding-top: /*the height of the absolutly positioned child*/ ;
position:relative;

If you add the following styles you should achieve what you want:

.user-match-container {
  position: relative;
  padding-top: 22px;
}

.match-owner {
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
  position: absolute;
  top: 4px;
  left: 0;
  right: 0;
}
