CSS making two divs equal height with display table

Question

In the following HTML, the div .left and .right have different heights. Is it possible to make both divs same height without defining the height. I have tried using display:table but does not work.

HTML:

<div class="wrap">

    <div class="left">
       Lorem    
    </div>

    <div class="right">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    </div>

</div>

CSS:

.wrap{
    overflow:hidden;
    width:250px;
    display: table;
    border-collapse: collapse;
}


.left{
    width:100px;
    float:left;
    display: table-cell;
    border-bottom:1px solid green;    
}


.right{
    width:150px;
    float:left;
    border-bottom:1px solid red;
    display: table-cell;     
}

Answer 1

Remove the float, which takes the elements out of the document's normal flow, and also add in another wrapper element, to act as the table-row:

table-cell, behaves like the <td> HTML element

Which implies that this requires (though I've not verified my inference) a display: table-row parent, as a td requires a tr parent-element.

.wrap{
    overflow:hidden;
    width:250px;
    display: table;
    border-collapse: collapse;
}

.row {
    display: table-row;
}
.left{
    width: 50%;
    display: table-cell; 
    background-color: #0f0;
}


.right{
    width: 50%;
    background-color: #f00;
    display: table-cell;     
}​
